1. Design of a fault-tolerant fractional slot PMSM for a vehicle application
Sammanfattning : In automotive applications, the PMSM is an interesting alternative due to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density since it is very important to save especially space but also weight in vehicle applications. LÄS MER
2. Modelling and design of electromechanical actuators for active suspension in rail vehicles
Sammanfattning : .... LÄS MER
3. Design and Evaluation of a Compact 15 kW PM Integral Motor
Sammanfattning : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. LÄS MER

5. Modeling and Analysis of PMSM with Turn-To-Turn Fault
Sammanfattning : Thanks to its high-torque density and high efficiency, the Permanent Magnet Synchronous Machine (PMSM) is today used in a vast range of applications, spanning from automotive to wind. Since in a PMSM the excitation field is provided by a permanent magnet instead of a coil, this machine does not have a rotor circuit and thereby the risk for electrical failures can be isolated on the stator circuit.
