Thesis deals with the challenges in the field of BLDC motors control with the utilization of Field Programmable Gate Arrays (FPGA). Using the modular dSPACE hardware with the FPGA board, these issues are solved: sensored and sensorless control, real-time simulation of BLDC motor and control of BLDC motor in degraded mode. FPGA design is made using the System Generator for DSP from Xilinx. The side effect of work is to show that with the expansion of high-level tools for FPGA design, the implementation of algorithms for FPGA is relatively quick and efficient and does not require years of experience and big knowledge of field programmable gate arrays. The implementation of algorithms on FPGA instead of processors brings many advantages, in the first place the high speed processing and low latency.

The thesis ,,DC motor control by PLC Simatic S7-1200“ focuses on the control of the DC motor using the programmable automatic machine PLC Simatic S7_1200 CPU1214C, designed by the German company Siemens, generating the PWM signal. The PWM is processed by the integrated circuit called the H-Bridge, which subsequently controls the DC motor.

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis proposes a remotely controlled motor drive system which is able to supply a regulated voltage for both DC and AC motors. The proposed system integrates two different technologies, each of which belongs to the field of wireless communications and semiconductor power electronics. The introduction highlights the literature review and technical contributions in these two electrical engineering fields. The pulse width modulated control algorithm for speed control is discussed in detail. Incorporating the zigbee wireless technology into the motor drive system, for the speed control of an AC and a DC motor, by implementing digital pulse width modulation technique is the aim of this thesis. The main characteristics of the proposed system are: 1) its universal feature since it can feed either DC or AC motor without changing the hardware, 2) remotely controlled, which allows the end-user to control the motor speed safely from a remote distance, 3) flexibility in installation of the motor drives in areas that are not easily accessible by end-users, and 4) uninterrupted speed control for distance of up to few 100 feet.

There is also explained how to measure engine parameters needed to calculate the transient.

Testning är en viktig del i tillverkningskedjan för att säkerställa kvalitet och funktion hos elektronikprodukter, och utförs ofta på flera nivåer innan den färdiga produkten lämnar fabriken. Produktionstester är rutinmässiga tester som tillämpas under masstillverkning och vid utformning av dessa måste tidseffektivitet prioriteras för att minimera negativ inverkan på produktionstakten. I detta projekt överfördes ett produktionstest för färdigmonterade borstlösa DC-motorer med drivelektronik till en ny testutrustning hos företaget Allied Motion. Testet skulle moderniseras och införas i företagets mjukvaruplattform uppbyggd i programspråket LabView. Testsekvensen kunde effektiviseras främst genom att kombinera dess delmoment och låta körningar av motorn användas för att testa flera egenskaper istället för att upprepas. Resultatet blev ett test som täckte in samma mätningar som i det äldre systemet med undantag för enstaka moment, samt mätte hastighet och momentkarakteristik med högre precision. Det omarbetade testet bestod av fyra deltester jämfört med tidigare tolv steg, och implementerades i fyra LabView-baserade testfall som kunde användas för att skapa en komplett testsekvens i plattformen. Uppgiften visade sig dock kräva mer tid och arbete än vad som uppskattats inledningsvis, och därför återstod flera av de arbetsuppgifter som planerats inom projektet att slutföra innan det nya testet skulle kunna tas i bruk i produktionen. / Testing is an important part of the manufacturing process to ensure the functional quality of electronics products, and is often performed in multiple stages during product assembly before the final product leaves the factory. Production tests are applied as a routine on all units in a production line, therefore time efficiency must be prioritized in the design of such tests in order to minimize the negative effect imposed on production rate. In this project an existing production test for fully assembled brushless DC motors was re-implemented for a new test equipment at Allied Motion. The purpose was to modernize the test and implement it in the company’s own LabView-based software platform. The test sequence was streamlined by combining and thereby reducing the number of steps, using the same motor runs to test multiple functions rather than repeating run sessions to collect data for similar test steps. The project resulted in a new test that, with a minor exception, covered the same measurements as in the old system and measured speed and torque performance with higher precision. The new test consisted of four partial tests instead of the earlier version’s twelve test steps, which were implemented in LabView-code as four separate test cases that could be used in creating complete test sequences in the software platform. The project task though turned out to require more time and effort than was initially estimated, and several parts that had been planned to be completed within the project time still remained before the test could be taken into use in the production line.

In today’s society, CNC machines are used for various purposes. In this project, a CNC plotter is created to analyze how the performance of the plotter differs when using two different motors: a DC motor controlled by a potentiometer in the horizontal direction and a stepper motor in the vertical direction. A CNC plotter is built and used to do tests in order to answer the research question. The results show that a DC motor with a potentiometer is more precise than a stepper motor and the mean value of the relative errors in the vertical direction is always higher. The values differ with 1 percentage point to 3 percentage points. The difference in the performance of the two motors depend on several factors and one of the main factors is considered to be the fact that the stepper motor sometimes skips steps. / I dagens samhälle används CNC-maskiner för olika ändamål. I detta projekt skapades en CNC-plotter för att analysera hur plotterns prestanda skiljer sig vid användning av två olika motorer: en DC motor kontrollerad av en potentiometer i horisontell riktning och en stegmotor i vertikal riktning. En CNC-plotter byggdes och användes för genomförande av tester för att kunna svara på forskningsfrågan. Resultaten visar att en DC motor med en potentiometer är mer exakt än en stegmotor och medelvärdet av de relativa felen i vertikala riktningen är alltid högre. Värdena skiljer sig från 1 procentenhet till 3 procentenheter. Skillnaden i prestanda för de två motorerna beror på flera faktorer och en av huvudfaktorerna anses vara det faktum att stegmotorn ibland hoppar över steg.

The purpose of this project was to construct a holonomic mobile robot driven with omni wheels. That would enable movement in all degrees of freedom. The finished product was a robot platform within a spherical shell body controlled by input commands defining speed and direction from a wireless communication medium. The platform was iteratively designed and constructed with parts made out of laser cut acrylic plastic. By using omni wheels powered by Direct Current (DC) motors, which will be described further, the holonomic drive could be realized as the wheel hubs were placed on the platform with calculated angles. / Syftet med detta projekt var att konstruera en holonomisk robot, vilket kan uppfyllas med hjälp av omnihjul som kan drivas i samtliga riktningar i planet.

Plattformen, som iterativt designades, laserskärdes ur akrylplast. På den placerades omni-hjul drivna av DC-motorer, vilka möjliggjorde den holonomiska rörelsen

In this thesis axial flux and radial flux brushless dc motors will be studied as a drive motor for the control of moment gyroscope wheel. Design equations for axial flux and radial flux brushless dc motor topologies will be reviewed. Based on these equations radial and axial flux motors with different number of poles will be designed that meet control moment gyroscope wheel application requirements. The results will be evaluated in terms of efficiency, torque/mass and torque/volume, and suitability for the control moment gyroscope application.
