1. Finite Control Set-Model Predictive control of Permanent Magnet Synchronous Motor
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The electrification of the transportation sector has been the most important goal of the current century. In the last decade, there has been a surge in the production and sale of electric vehicles, necessitating substantial research and development in the industry. LÄS MER
2. Development of an experimental six-phase induction machine drive
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. LÄS MER
3. Online Parameter Estimation of a Six- Phase Machine for Marine Application
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. LÄS MER
4. Torque Ripple Analysis and Compensation of Servo Drives for Robot Application
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. LÄS MER
5. Evaluation of a Switched Reluctance Machine in an Automotive Oil Pump Application
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : A Switched Reluctance Machine (SRM) is evaluated in terms of torque quality and speed ripple for a particular pump application. The aim is to give BorgWarner insight into the control methodology and possible applications for a Switched Reluctance Machine. LÄS MER
