Thesis submitted in fulfilment of the requirements for the degree Master of Education: Visual Art Education in the Faculty of Education at the Cape Peninsula University of Technology, 2012 / This thesis investigates the factors, specifically the constraints, that influence the choices intermediate phase teachers make when planning visual art lessons. The study is also concerned with how teachers deal with factors that they identify as constraints to teaching visual art. The study is framed within an interpretive framework and the work on teacher knowledge by Shulman (1986; 1987). Semi-structured interviews were conducted with four class teachers, three Arts and Culture teachers, and four visual art teachers using a phenomenological methodology. Interviews were analysed systematically by indexing and organizing the data using the knowledge base for teaching as described by Shulman (1987) and Turner-Bisset (1999).<p></p> The patterns in what teachers consider when planning visual art lessons, and their reasons for doing so, was better explained by a teacher’s training in visual art education rather than his/her role as a class, Arts and Culture, or visual art teacher. In this study, the teachers who are trained in visual art education generally work in situations with few contextual problems and their focus, when lesson-planning, centres around the best way visual art content knowledge can be integrated into lessons. In comparison, most of the teachers who are not trained in visual art education mentioned numerous contextual problems that affected their ability to teach visual art. These teachers plan their visual art lessons around what they believe they are able to manage within the context of the school they are working in, rather than specific visual art related outcomes. In addition, their lesson-planning decisions are generally based on limited visual art content knowledge and pedagogy. Hence, compared to teachers trained to teach visual art, their application of visual art content knowledge is haphazard and does not build on the foundation of the curriculum.<p></p> Limited contact time and support from management are two contextual factors that were found to impact the way teachers in this study plan visual art lessons. To mitigate for the lack of contact time, the teachers trained in visual art education endeavoured to manage their lesson time efficiently and to setup clear routines with their learners so as to minimize the amount of time spent on non-learning activities.

Thesis (MTech(Environmental Health))--Cape Peninsula University of Technology, 2011. / Pharmaceuticals have been formulated to influence physiological systems in humans, animals, and microbes but have never been considered as potential environmental pollutants by healthcare professionals. The human body is not a barrier to chemicals, but is permeable to it. Thus after performing their in-vivo functions, pharmaceutical compound introduced into the body, exit mainly via urine and faeces. Sewage therefore contains highly complex mixtures of chemicals in various degrees of biological potency. Sewage treatment works including those in South Africa, on the other hand, are known to be inefficient in removing drugs from sewage and consequently either the unmetabolised pharmaceutical compounds or their metabolites emerge in the environment as pollutants via several trajectories. In the environment, the excreted metabolites may even undergo regeneration to the original parent molecule under bacterial influence, resulting in “trans-vivo-pharmaceutical-pol ution-cycles”. Although all incinerators are known to generate toxins such dioxins and furans from the drugs they incinerate, all the medicines disposed by the hospitals under research, were incinerated, as the preferred option of disposal. The incineration process employed was found to be environmentally unsafe. Expired and unused medicines which the general public discard as municipal solid waste become landfilled. Because many landfill sites are not appropriately engineered, the unwanted drugs landfilled therein, leach into the surrounding ground water, which is the influent source of water treatment plants. Water treatment plants, including those in South Africa, are also inefficient in eliminating pharmaceutical compounds, releasing them in sub-therapeutic concentrations into potable tap water as pollutants, the full effects of which are yet to be determined.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology Chemistry in the Faculty of (Science) Supervisor: Professor T.N. van der Walt Bellville campus Date submitted: October 2011 / It is important to quantify polymeric components in a coating because they greatly influence the performance of a coating. The difficulty associated with analysis of polymers by Fourier transform infrared (FTIR) analysis’s is that colinearities arise from similar or overlapping spectral features. A quantitative FTIR method with attenuated total reflectance coupled to multivariate/ chemometric analysis is presented. It allows for simultaneous quantification of 3 polymeric components; a rheology modifier, organic opacifier and styrene acrylic binder, with no prior extraction or separation from the paint. The factor based methods partial least squares (PLS) and principle component regression (PCR) permit colinearities by decomposing the spectral data into smaller matrices with principle scores and loading vectors. For model building spectral information from calibrators and validation samples at different analysis regions were incorporated. PCR and PLS were used to inspect the variation within the sample set. The PLS algorithms were found to predict the polymeric components the best. The concentrations of the polymeric components in a coating were predicted with the calibration model. Three PLS models each with different analysis regions yielded a coefficient of correlation R2 close to 1 for each of the components. The root mean square error of calibration (RMSEC) and root mean square error of prediction (RMSEP) was less than 5%. The best out-put was obtained where spectral features of water was included (Trial 3). The prediction residual values for the three models ranged from 2 to -2 and 10 to -10. The method allows paint samples to be analysed in pure form and opens many opportunities for other coating components to be analysed in the same way.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Consumer Science: Food and Nutrition in the Faculty of Applied Sciences at the Cape Peninsula University of Technology 2012 / The chronic diseases of lifestyle, tuberculosis and Human immunodeficiency virus/Acquired immunodeficiency syndrome have a high prevalence in South Africa. These diseases are characterised by oxidative stress and a chronic inflammatory state that contribute to both the development and the acceleration of these diseases. Research into the phytochemical plant food components suggest that these substances could possibly play a vital role in the prevention of such disease. Corn steep liquor (CSL) is a waste product with an exceptionally high polyphenol content and total antioxidant capacity (TAC). This led to the suggestion that it could be utilised in the development of food products with functional food characteristics. Stock cubes, due to the widespread use among consumers of different socio-economic backgrounds, were identified as vehicle for the delivery of the CSL with its phytochemical content. This lead to the development of a stock cube utilising CSL as a source of phytochemical polyphenolic antioxidants with the micronutrients zinc, selenium and copper as added support to immunonutrition, along with iron due to the wide spread prevalence of iron deficiency in the South African population. The acceptability of the developed stock cube was tested by preparing savoury rice and pea soup and having blue collar (n = 50) and white collar (n = 49) participants rate the acceptability on a 9-point hedonic scale, ranging from “dislike extremely” to “like extremely”. The savoury rice received a 41% “like very much” rating followed by a 24% “like moderately” rating. The pea soup was rated even more positively as it received a 42% “like very much” rating and a 29% “like extremely” rating. In addition, among the blue collar participants, significant (p < 0.05 for each) findings occurred with a greater liking of the sample dishes prepared with the developed stock cube by participants of the ethnic Black grouping, with Xhosa as home language and being married, as well as those participants who habitually prepare the meals in the household. A significant (p < 0.05) finding with the white collar participants was a greater liking of the sample dishes prepared with the developed stock cube among those participants who would be willing to make use of a stock cube with health benefits. The developed stock cube was also subjected to six months accelerated shelf-life stability testing, reflecting twelve months real time storage. The parameters measured were microbial growth, oxidative rancidity, antioxidant status and organoleptic changes. All microbial growths tested remained within the acceptable specification ranges. Oxidative rancidity, measured as the peroxide value, was detected analytically at the fifth and sixth samplings, but was not detectable organoleptically. The antioxidant status, measured as the TAC and the total polyphenol content, remained relatively stable during the testing period. Though no noticeable organoleptic changes were observed during the stability testing, there was a darkening of the colour by the second sampling. The results of the acceptance testing, as well as the shelf-life stability testing, support the conclusions that the study objectives of developing a stock cube with functional food characteristics and it being received positively by consumers were achieved.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology Consumer Science: Food and Nutrition in the Faculty of Applied Sciences at the Cape Peninsula University of Technology 2013 / Consumer debt has escalated in South Africa ever since the country sank into a recession in early 2009. One of the many consequences of this economic downturn has been a major increase in energy, transport and food prices. Food-buying strategies can be used by consumers to help to reduce the amount of money, which is spent on food, and increase funds that are available for other household expenses. The main objective of this study was to determine the use of four pre-selected food-buying practices by consumers who reside in different socio-economic status (SES) areas in the City of Cape Town. Residents of lower SES areas have been found to have purchasing patterns that are different to those who live in higher SES areas. The subsidiary objectives were to further establish whether there is a difference in the use of food-buying practices by consumers who reside in different SES areas, and to ascertain whether shopper and demographical characteristics have an influence on the use of food-buying practices among consumers in general as well as among consumers within the same SES area. A consumer intercept survey was conducted after being granted ethics approval. Three groups of respondents that represent a low, middle and high SES area were systematically sampled. A total of 1 200 consumers (95% response rate) who are older than 18 years anonymously and voluntarily participated in the study, which was conducted at pre-selected stores in the suburban areas of Delft (low SES area), Maitland (middle SES area) and Meadowridge (high SES area) in the City of Cape Town. These areas and stores were selected to represent the SES of households or consumers, respectively, based on the demographic and employment profile that was provided for each by Statistics South Africa‟s 2001‟s census profiles. The data was collected by using a pilot tested structured, self-administered questionnaire consisting of mainly multiple-choice questions, which gathered information from the respondents regarding their shopper and demographic characteristics, as well as their frequency of use of the four food-buying practices (represented by six structured questions each) as: (i) use of a shopping list; (ii) use of advertisements to plan shopping; (iii) comparison of prices amongst different brands; and (iv) avoidance of impulse buying. These food-buying practices were selected based on available consumer education literature, which focused on the use of these food-buying practices and a pilot study that was conducted in 2011, which indicated that these four practices were most frequently used by the consumers who were surveyed. Within each SES area most of the Cronbach‟s alpha coefficients that were obtained were >0.9 among the six questions, which represented each food-buying practice, and reflected strong internal consistencies among the questions. The Generalised Linear Model analysis of variance utilising the Wald statistic, which is based on the chi- square distribution and Bonferroni pair-wise comparisons, were used to determine significant differences between respondents‟ use of the food-buying practices and their SES area group, as well as their shopper and demographic characteristics. A significant level of p<0.001, as well as p<0.05 was used. Most (60 to 80%) of the respondents in each SES area are female. Within the total sample, low and middle SES areas a majority (62 to 73%) of the respondents were between 26 to 55 years of age, whereas in the high SES area a majority (63.5%) of the respondents were 46 years and older. In general, more than half (52 to 56%) of the respondents were married and most (38 to 55%) were employed full-time and had household sizes, which mainly (18 to 23%) consist of two to four members. Regarding highest level of education attained, most of the respondents in the total sample either had a Grade 8 to 11 (37.6%) or a Grade 12 (24.7%), whereas most (54%) respondents in the high SES had either acquired a post-matric diploma or certificate, degree or post-graduate degree. Most (67 to 89 %) of the respondents within the total sample, middle and low SES area associated themselves with the Coloured population group, whereas most (56.7%) of the respondents in the high SES area associated themselves with the White population group. Concerning household monthly income, two thirds (65%) of the respondents within the high SES area had an income of R12 801 upward; most (77.5%) of the respondents within the middle SES area had an income of R801 to R12 800 per month; and more than half (57%) of the respondents in the low SES area received an income of R800 to R3 200 per month. In general, most respondents indicated that they shopped for food once a week (33 to 48%); took less than half an hour to shop for food (40 to 52%); and usually shopped alone for food (68.9%). Cash was the most prevalent means of payment among respondents within the total sample (66.7%), middle (70.5%) and low (93%) SES areas, while most (43.2%) respondents in the high SES area paid by means of a debit card. Among the respondents who reside in the different SES suburban areas, differences in the use of food-buying practices were revealed. Respondents within the high (p<0.001) and middle (p<0.05) SES areas displayed a higher propensity to use a shopping list, yet a lower propensity to use advertisements compared to respondents within the low SES area. Respondents within the low and particularly middle SES area displayed a higher propensity to compare prices (p<0.05) compared to respondents within the high SES area. No differences (p>0.05) for the avoidance of impulse buying as a food-buying practice were found among respondents within a low, middle and high SES area. A largely low propensity to avoid impulse buying was found. Regarding shopper characteristics, the respondent payment method influenced the use of a shopping list (p<0.05), use of advertisements (p<0.05 and p<0.001 between the payment methods) and propensity to avoid impulse buying (p<0.05) as food-buying practices within the low SES area. Among respondents, in general, the payment method influenced the avoidance of impulse buying (p<0.05) as a food-buying practice. The length of time that it took to shop influenced the use of a shopping list (p<0.05) as a food-buying practice within the low SES area and the propensity to compare prices of different brands (p<0.05) as a food-buying practice within the middle SES area. Shopping frequency influenced the use of advertisements (p<0.05) as a food buying practice within the low SES area and co-shopping influenced the propensity to avoid impulse buying (p<0.05 and p<0.001 between the various co-shoppers) as a food-buying practice within the low SES area, as well as the propensity to use advertisements (p<0.05) as a food-buying practice within the high SES area. Gender influenced the use of a shopping list (p<0.05) as a food-buying practice within the high SES area and the use of advertisements (p<0.05), as well as the propensity to avoid impulse buying (p<0.001) as food-buying practices within the middle SES area. Gender also affected the propensity to compare the prices of different brands (p<0.05) as a food-buying practice within the low SES area and among respondents, in general, the propensity to avoid impulse buying (p<0.05), as well as the use of advertisements (p<0.001) as food-buying practices. Employment status affected the use of a shopping list (p<0.05) as a food-buying practice within the high SES area. Population group affected the propensity to use advertisements as a food-buying practice within the low SES area (p<0.05 and p<0.001 between the population groups) and among the respondents, in general, (p<0.05). Household monthly income affected the propensity to compare the prices of different brands (p<0.05) as a food-buying practice within the high SES area. Among the respondents, in general, household monthly income affected the propensity to compare the prices of different brands (p<0.05 and p<0.001 between the income groups) and the use of advertisements (p<0.05) as food-buying practices. The study confirmed that there are differences in the use of food-buying practices among consumers who reside in different SES areas, and further identified specific shopper and demographic characteristics that have an effect on consumers‟ (in general, as well as within the same SES area) use of food-buying practices. Since food-buying practices can be used by consumers to manage their household income expenditure on food, consumer awareness of these practices, in particular the avoidance of impulse buying should be promoted through educational efforts ideally by food retail companies. These companies have the resources and capability to communicate with consumers regularly (while shopping in-store), and can inform their customers about food-buying practices that would help them to save money and/or make additional funds available for other essential household expenses.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Horticultural Sciences in the Faculty of Applied Sciences at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY Supervisor: Dr L Kambizi Co-supervisor: Dr NP Makunga Cape Town December 2013 / Agathosma betulina (Berg.) Pillans, previously known as Barosma betulina, is a member of the Rutaceae family, and indigenous to the fynbos botanical biome of the Western Cape of South Africa. It is commonly known as buchu. Extracts as well as powdered leaves have traditionally been used for the treatment of various ailments. The increase in the international demand for A. betulina for health as well as food and beverage benefits, have raised concerns over exploitation of wild populations and the lack of horticultural information necessitates this study to evaluate the propagation of this economical important species. The main objective of this study was to establish a simple and highly productive micropropagation protocol for A. betulina through experimenting with nodal explants. Testing of the effect of various treatments (physical scarification, chemical scarification, GA, stratification, smoke and combinations thereof) on the in vitro germination of A. betulina seeds was done to elucidate the factors which control seed germination. The study revealed that the physical scarification and smoke-induced germination had a significant effect on germination percentages. In terms of germination rate, the radical generally started to appear after approximately 10 days in the physical scarification with smoke treatment. Initial decontamination methods with the exposure of various concentrations of NaOCl gave fatal results, however 1.5% NaOCl had more phenolic reactions rather than fungal or bacterial contamination. Interestingly, contamination rates of explants were influenced by the stage of maturity of the explant material. This plant material was used to test different strengths of regeneration media, to ensure that the explants receive ample nutrients. Results made exhibited that ½ MS was the best strength for growing A. betulina nodal explants. Compared comparison between in vitro derived explants and ex vitro collected explants showed that the ex vitro derived explants had significant results, but the explants lost vigour soon after the initial exponential growth leading to the explants dying off. Furthermore, ex vitro decontaminated plant material was not economically viable to continue with. Seedlings derived from germinated seeds appeared to be the preferred method of propagation as this spent the least time in culture and produced a stable plant with an established root system, which is essential during the hardening off process after in vitro growth. When exposing nodal explants to phytohormone 2,4-D it responds best to dosages 0.5mg Lˉ¹ and 1mg Lˉ¹. Phytohormone BA was very effective in producing soft friable callus. The best results were shown when 0.5mg Lˉ¹ BA was applied to ½ MS media. For both shoot length and multiple shoot production, a combination of phytohormones BA-NAA (1: 0.5mgLˉ¹) had the most significant results. Interestingly, a higher phytohormone concentration of NAA is necessary to develop multiple adventitious roots. The effect of 3mg Lˉ¹ was significant in that it resulted in multiple adventitious roots, but fewer calli was observed in this treatment. Micropropagation becomes valuable as little attention between subcultures is needed; making it less labour intensive compared to conventional nursery propagation systems where weeding watering and spraying of plants are labour intensive. In the traditional world of medicine, more so in Southern Africa, extracts are prepared by adding boiling water to the plant material; however commercial ethanol is used as an extractant. Establishment of the essential oil quality of the in vitro cultures post exposure to various treatments was done. Analysis of essential oils from A. betulina resulted in the identification of twenty one compounds. The results showed qualitative as well as quantitative differences amongst the samples used in the study. The highest relative concentration of limonene was observed in the callus of nodal explants after it was exposed to 0.5mg lˉ¹ NAA. No pulegone was found in this treatment making it ideal for limonene production. This suggests that liquid culture with the same treatment may produce more calli making it ideal for the production of limonene.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Civil Engineering in the Faculty of Engineering at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY 2014 / The current problems of orifice, nozzle and Venturi flow meters are that they are limited to turbulent flow and the permanent pressure drop produced in the pipeline. To improve these inadequacies, converging-diverging (C-D) tubes were manufactured, consisting of symmetrical converging and diverging cones, where the throat is the annular section between the two cones, with various angles and diameter ratios to improve the permanent pressure loss and flow measurement range. The objective of this study was firstly to evaluate the permanent pressure loss, secondly to determine the discharge coefficient values for various C-D tubes and compare them with the existing differential pressure flow meter using Newtonian and non-Newtonian fluids, and finally to assess the performance of these differential pressure flow meters. The tests were conducted on the multipurpose test rig in the slurry laboratory at the Cape Peninsula University of Technology. Newtonian and non-Newtonian fluids were used to conduct experiments in five different C-D tube flow meters with diameter ratios (β) of 0.5, 0.6 and 0.7, and with angles of the wall to the axis of the tube (θ) of 15°, 30° and 45°. The results for each test are presented firstly in the form of static pressure at different flow rates. It was observed that the permanent pressure loss decreases with the flow rate and the length of the C-D tube. Secondly, the results are presented in terms of discharge coefficient versus Reynolds number. It was found that the Cd values at 15° drop earlier than at 30° and 45°; when viscous forces become predominant, the Cd increases with increasing beta ratio. The Cd was found to be independent of the Reynolds number for Re>2000 and also a function of angle and beta ratio. Preamble Performance of a symmetrical converging-diverging tube differential pressure flow meter Finally, the error analyses of discharge coefficients were assessed to determine the performance criteria. The standard variation was found to increase when the Reynolds number decreases. The average discharge coefficient values and their uncertainties were determined to select the most promising C-D tube geometry. An average Cd of 0.96, with an uncertainty of ±0.5 % for a range of Reynolds numbers greater than 2,000 was found. The comparison between C-D tubes 0.6(15-15) and classical Venturi flow meters reveals that C-D 0.6(15-15) performs well in turbulent range and shows only a slight inaccuracy in laminar. This thesis provides a simple geometrical differential pressure flow meter with a constant Cd value over a Reynolds number range of 2000 to 150 000.

Thesis submitted in fulfillment of the requirements for the degree Master of Technology: Electrical Engineering in the Faculty of Engineering at the Cape Peninsula University of Technology 2013 / The development of power electronics did remove most of technical limitations that high voltage direct current (HVDC) used to have. HVDC, now, is mostly used for the transmission of bulk power over long distances and for the interconnection of asynchronous grid. Along with the development of the HVDC, the growth of power demand also increased beyond the utilities capacities. Besides the on-going increasing of power demand, the reforms in electricity market have led to the liberalization and the incorporation of Independent power providers in power system operation. Regulations and rules have been established by regulating authority for grid integration of Independent power providers. With the expected increase of penetration level of those new independent power providers, result of economic reason and actual green energy trend, best method of integration of those new power plants are required. In this research HVDC technology, namely VSC-HVDC is used as interface for connecting independent power providers units to the grid. VSC-HVDC has various advantages such as short-circuit contribution and independent control of active and reactive power. VSC-HVDC advantages are used for a safe integration of IPPs and make them participate to grid stabilization. MATLAB/Simulink simulations of different grid connected, through VSC-HVDC system, IPPs technologies models are performed. For each IPP technology model, system model performances are studied and dynamics responses during the disturbance are analyzed in MATLAB/ Simulink program. The simulation results show that the model satisfy the standard imposed by the regulating authority in terms of power quality and grid support. Also the results show the effect of the VSC-HVDC in preventing faults propagation from grid to integrated IPPs units.

Submitted to the Department of Electrical Engineering in Fulfilment of the Requirements for the Magister Technologiae in Electrical Engineering at the Cape Peninsula University of Technology SUPERVISOR: E. VOSS NOVEMBER 2013 / The reluctance synchronous machine (RSM) operates on the principle of magnetic reluctance, which is produced through a careful selection of rotor flux barriers and cut-outs. Magnetic reluctivity is the resistance to magnetic flux and can be directly related to the principles of Ohm’s law in electrical circuits. Although reluctance motors have been known for more than 150 years, researchers lost interest when Nikola Tesla’s induction machine (IM) was introduced to industry. Over the last few decades, however, RSMs have shown a lot of potential. They are cheap, robust, reliable, and their rotors can also be used in the stators of IMs. The disadvantage of these machines is an inherently high torque ripple, being the result of its rotor geometry, but the biggest advantage is having a significant reduction in copper losses after the rotor cage has been removed. This advantage drove engineers to investigate, optimise and modify the performance and structure of this machine, which led to the usage of electronic drive systems. The recent advances in technology have allowed researchers to further investigate and modify the design and performance of this special type of machine, with the integration of Finite Element Analysis (FEA) software also making a contribution to the development of the RSM’s current driven systems. The voltage-fed RSM, driven direct-on-line (DOL) from the utility supply, was left in the shadows as the current-fed RSM took reign, but still is, in the author’s opinion, not yet fully analysed. This thesis practically investigates the performance characteristics of the cageless, voltage-fed 3kW RSM in its steady-state operation, under various loads. These performance characteristics are also compared to a RSM driven from a sensorless vector drive (current-fed) to investigate the advantages and disadvantages between the two. Experiments performed on the test bench immediately reveal a limitation to the voltage-fed RSM’s ability to drive higher loads. While the current-fed RSM conveniently reaches 150% of its full-load, the voltage-fed RSM, due to its cageless structure, only reaches 110% of its full-load power. Despite this discovery, the voltage-fed RSM proves to have a lower core loss, harmonic content and torque ripple. Using a FE software package with an integrated source-code, additional parameters such as the dq-axis inductances and currents are also compared and analysed in terms of its reaction to an increase in load. The eddy-current, hysteresis and excess losses are also analysed as well as the harmonic components caused by the geometry of the RSM. For academic purposes, a fair amount of emphasis is placed on the approach to the problem. The preparation for the FE simulation is explained in detail, providing insight into the FE mathematical model as well as parameter acquisition. These parameters include current angle, friction and windage losses, stator resistance, end-winding leakage reactance, core loss and inertia. The results obtained by the FE model are compared to that of the measured results and is found to have an error of only 0.52%. Furthermore, this study attempts to find the feasibility of the voltage-fed RSM’s practicality in modern-day industry. The conclusion is drawn that the voltage-fed RSM could be used as a more elegant alternative to an otherwise over-complicated and over-priced installation.

Submitted to the Department of Electrical Engineering in Fulfilment of the Requirements for the Magister Technologiae in Electrical Engineering at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY SUPERVISOR: E. VOSS NOVEMBER 2013 / Radial and peripheral displacement of stator teeth in electrical machines is known to be the cause of undesired vibration which leads to noise. This thesis serves to investigate the possibility of physically measuring the radial displacement of stator teeth caused by electromagnetic forces which, to the author’s knowledge, has not yet been achieved. A simplified practical approach is adopted in order to address the inherent difficulties attached to this problem, and the measurement of displacement is done by means of an experimental rig where a tooth is subjected to magnetic force acting over an air gap. Three experiments are carried out, each comprising ten tests, the results of which are compared in order to gain some idea as to the magnitudes of displacement which can be expected over a range of applied air gap flux densities. The aim of this work is to observe the displacement response of magnetised EM core material when acted upon by forces, and to see if the measured results agree with the elastic displacement predicted by a wellknown formula. It will be shown that although the measured results are in the same range as the predicted results, there is a deviation from the predicted linearity due to certain characteristics of the force rig, which are explained. The chosen measurement method is capacitive displacement and is shown to be a viable alternative to the more commonly used search coils and vibrometers in past literatures, especially when measuring displacements on the nano-scale. In addition, this study shows the importance of using 3D finite element software to simulate the electromagnetic model when saturation is present in the core of the test specimen. The important findings of this work are discussed in detail, and some ideas put forward, in an attempt to establish a starting point for future related work in the measurement of electromagnetic forceinduced displacement of stator teeth in electrical machines.
