This thesis presents the design of a scratch drive actuator (SDA) for Micro Motor Application. In accordance with the force needed to drive the mechanism, the relationship among SDA output force, geometries, and applied voltage is first constructed by employing the principle of virtual work. Having selected the topology of the device, the equations governing the motions and the forces of the micro motor and the actuator can be derived. The SDA and the associated micro motor mechanism are designed by considering the characteristics of Multi-User MEMS Processes, or MUMPs fabrication process. There are several types of SDA used for step motor application being designed and fabricated as illustrative samples. The chip well defined in MUMPs is released by immersing the chip in a bath of HF. It is followed by cleaning in DI water and IPA on a hot plate at 150¢J to reduce stiction.¡@The samples are inspected by OM and SEM, respectively.¡@The experimental and analytical results indicate the practicability of the proposed design concept.

This thesis focuses on compact brushless DC fan motor, drive circuit structure of motor is proposed, several functions such as output low current limit circuit and low rotation speed limit are added in order to increase robustness of drive circuit. Besides, speed feedback controller is used to solve several problems such as high frequency full speed exciting noise and high power dissipation which occurs in open loop rotation speed control circuit.With regard to BLDC fan motors generally use Hall sensor to detect rotor position, this research proposes sensorless control technology for the purpose of reducing circuit cost and motor size.

The objective of this thesis is to provide the systematic design procedure for a high-speed PM motor with portable sizes, along with the detailed mathematical model developments and the thorough operational analysis. The entire scheme is realized by first following an available design reference to estimate the desired machine physical structures. Then, based on the related field theory, recoil line characteristics of permanent magnets, and the magnetic equivalent circuit method, the system mathematical model can be devised. Finally, the system operational behaviors can be investigated by the devised analytical models, and their accuracies will also be confirmed by the reference design tool. It is believed that the proposed design and verification scheme can provide a valuable and reasonable guidance for the related industry application.

This thesis focues on the realization of small size brushless DC fan motor driving circuit, adding the protection circuit of commutation to H bridge, in addition, the function of low current limiter, and slow rotation speed limiter are also implemented to the more stable rotation. With regard to the strategy of rotation speed control, we use speed feedback controller to slove noise problem which occurs in high frequency full speed excited and adopt thermistor accompanied with the voltage divided circuit to achieve speed control with temperature. Finally, for the sake of reducing the cost and shrinking the size of system, the design of sensorless mode is proposed and the rotation speed control system is realized under sensorless mode.

In 1970¡¦s, by applying the field-oriented analysis method, the decoupling of motor speed (motor torque) and rotor flux is obtained. However, the performance is rather sensitive to the variation of motor parameters, especially the motor time constant, which varies with the temperature and saturation of magnetizing inductance. In this thesis, the model following based £g design for induction motor speed control is studied. Roughly speaking, the model following component provides a reference model with desired closed-loop performance and the £g component provides a systematic synthesis procedure so that, under practical uncertainty and load disturbance, the goal of asymptotic model following is achieved.

The objective of this thesis is to integrate available commercial Software/Hardware package and to establish appropriate graphic user interface (GUI) for transverse flux linear switched-reluctance machine (TFLSRM) motion control. By changing the machine feedback signals, package will be matched with TFLSRM. The control unit of the whole system is based on digital signal processor (DSP) with its software interface being built up by Matlab/Simulink. Hence, users can operate this machine directly by observing the output result from computer monitor. By combining with suitable PI controller, friction variation can be eliminated and the control objectives of the TFLSRM under a desirable velocity also can be achieved.

With Taiwan¡¦s accession to the World Trade Organization (WTO), foreign-based oil manufacturers will join, in succession, the motor oil market in Taiwan. This will definitely push further the competition for business that has been made intense by a large number of domestic manufacturers. Therefore, it will be necessary to analyze consumers¡¦ behavior in buying motor oil in order to promote and sell this product. This research examined consumers¡¦ sex, age, education, occupation, and monthly income and investigated whether differences in these factors would lead to significant differences in suggestions and perception, in methods of collecting information and the degree of involvement in the evaluation of plans, and in post-purchase satisfaction and loyalty of reference groups related with motor oil products and prices under different situations. Drivers of small cars registered with Kaohsiung County and Kaohsiung City were, based on convenient sampling, taken as the subjects that received questionnaire survey. The collected data underwent statistical procedures and analysis, and conclusions and suggestions were drawn and put up to be adopted by concerned enterprises to maintain their market shares and even enhance their competitive edge. The research has obtained findings and offered suggestions that follow: ¤@¡BFindings: ¡]¤@¡^¡BFemales are more likely than their male counterparts to purchase products at bargain prices, and when they are satisfied with the quality of a motor oil product, they are more likely to purchase the same product in the future. ¡]¤G¡^¡BConsumers younger than 30 are more likely to purchase products at bargain prices and more heavily influenced by price suggestions offered by others. ¡]¤T¡^¡BConsumers with college or graduate education are more heavily susceptible to positive remarks than to negative remarks. These consumers consider products to be better in quality if their manufacturers provide better product information. They are more likely to buy motor oil products that have been advertised and promoted in humorous term ¡]¥|¡^¡B Consumers that are engaged in manufacturing have better chance to purchase products at bargain prices. They are more likely to purchase the products that they have used and felt good about the quality and price. On the other hand, if they are not satisfied in these two areas, they will be very likely to switch to other products. ¡]¤­¡^¡BIn purchasing a motor oil product at bargain prices, consumers with low income are more concerned about the evaluation of this product after using it. ¤G¡BSuggestions: ¡]¤@¡^¡BOil manufacturers should enhance their R & D capability, increase the popularity of their products, appeal to customers in humorous ways, and pack products properly and offer them at competitive prices. ¡]¤G¡^¡BOffer various sources of information about products to which consumers have easy access, and gain consumers¡¦ satisfaction with product quality and price so as to win their loyalty.

The research method of this thesis is Case study and Yulon Motor Co. is an example for this case study. In order to find out the Yulon motor Co.¡¦s organization, constitution of departments and each different situation at that time, I collect the organizational charts which are about fifty years from the beginning of this company until now and the other inside historic data. By analyzing these data, I summarize the process of the organizational growth and change of Yulon motor Co. Therefore; there are some key points as the following: To begin with, the main organizational structure of Yulon motor Co. is by function. It sets up the benchmark of the complete organizational systems for motor industry in Taiwan, including: research & development, manufacturing and marketing system. Second, organizational tasks at each period would affect the adjustment of organizational structure. There are some main periods as the following: 1.The period was from 1951 to 1971-----Making the Wheel for Taiwan According to this task, the organizational structure was established at manufacturing and increased a few departments and responsibilities based on the needs of production. 2.The period was from 1981---Designing the automobile for Chinese and regain the rights of dealer business When the manufacturing technology was achieved to some level, the designing capability of motor outline was the main competition with the other motor companies. Immediately, Yulon Motor Co. set up the first design center compared with the other motor companies. In the meanwhile, it closed the relationship of dealer business with China Auto Co. Therefore, Yulon Motor Co. rebuilt the network of dealer business all over the Taiwan. It also led the inside of Yulon Motor Co. to reorganize the organizational structure of marketing system. 3.The period was from 1991----relocating the factory and office and reducing the business cost At the end of the 1994, Yulon Motor Co. relocated the other factories, center and office at San-Yi. At the same time, Company combined the same function on the organization and integrated the organizational structure into four systems, including: research & development, manufacturing, marketing and management system to reduce the business cost. This adjustment of the organizational structure made the Yulon Motor Co. abbreviate its original organizational structure and got a positive response from market. 4.The period was from 2001---to be a leader of motor moving value chain at Chinese market Owing to open market in Mainland China, designing the Chinese style on automobile is the main competition in the future. That¡¦s the reason why Yulon Motor Co. focuses on Chinese market as a company¡¦s vision. Third, the history of changing process on the organization of Yulon Motor Co. matches the research of Lawrence & Lorsch. From the history of Yulon Motor Co., it¡¦s easy to find out that the adjustment of organizational structure such as manufacturing, research & development and marketing would be changed by timing, environment and productive technology to achieve the organizational goals or to deal with the competitive outside environment. This kind of adjustment of organizational structure matches the survey¡¦s outcomes of Lawrence & Lorsch. It said that each department on the organization would develop its own function and structure to deal with the variety of outside environment. This survey investigates the ten companies at three different departments, including manufacturing, research & development and marketing department. At last, there are two main strategies for Yulon Motor Co. to overcome the obstacle of communication at different departments: 1.Set up a committee or a meeting of cross function team. 2.Do job rotation.

Three experiments compared learning of relative and absolute timing of a sequential key-pressing task by physical and observational practice. Experiment 1 compared a task with a complex internal structure (goal proportions of 22.2, 44.4, 33.4 on the three movement segments) to one with a simpler structure (goal proportions of 33.3, 33.3, 33.4). Observers only learned the relative timing as well as physical practicers when the internal structure was simple, but learned the absolute timing in both conditions. Experiment 2 compared variable (700, 900, and 1100 ms overall time) with constant practice (900 ms overall time). Observers of constant practice models learned the relative timing better than no-practice control participants, but not as well as the models, while observers of variable practice models learned the relative timing no better than the control group. Observers in both practice conditions were able to produce the absolute timing as well as those who physically practiced. In Experiment 3 observers of an expert model were able to produce the relative timing as well as those who physically practiced the skill, while those who observed learning models were not. All observers and the physical practice participants were able to produce the overall duration as well as the expert model. The results of these three experiments support earlier findings that increasing stability during practice promotes better learning of relative timing, but that absolute timing can be learned under less-stable conditions (Lai, Shea, Wulf, & Wright, 2000b). These findings also have important implications on the limitations of Scully and Newells' (1985) prediction that relative timing, but not absolute timing, could be learned by observation. Experiments 1-3 along with earlier findings (Black & Wright, 2000) have consistently found that absolute timing could be learned by observers even as the nature of the task, practice schedule, and model are manipulated. Furthermore, the results suggest a limitation to the effectiveness of learning models (Adams, 1986; McCullagh & Caird, 1990).

A contemporary view of early childhood motor development considers environmental influences as critical factors in optimal growth and behavior, with the home being the primary agent. However, minimal research exists examining the relationship between motor development and the home. The present dissertation addresses this gap with the goal of creating an innovative parental self-report instrument for assessing the quality and quantity of factors (affordances and events) in the home that are conducive to enhancing motor development in children ages 18-to-42 months. In Study 1, following initial face validity determination, expert opinion feedback and selective pilot-testing, construct validity was examined using 381 Portuguese families. Factor analysis techniques were used to (1) compare competing factorial models according to previous theoretical assumptions, and to (2) analyze the fit of the preferred model. Of the five plausible models tested, the 5-factor solution provided the best fit to the data. Reliability was established through the scale reliability coefficient with a value of .85. Study 2 tests for the content validity of the instrument, examining the relationship between the inventory and level of motor development. Fifty-one (51) participants from the original sample were assessed for motor development using the Peabody Developmental Motor Scales II (PDMS2). Comparisons were made between the PDMS2 classifications of the AHEMD-SR quartile groups. Results supported the primary hypothesis, that is, less favorable motor development was associated with less availability of home affordances. Furthermore, the interaction of (factors) Inside Space and Variety of Stimulation was significantly related to both Gross and Total Motor Development scores. The findings of these two studies suggest that the AHEMD-SR is a valid and reliable instrument for assessing how well home environments afford movement and potentially promote motor development.
