2. 1. Design of a fault-tolerant fractional slot PMSM for a vehicle application

   Author : Christian Dubar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PMSM; Efficiency; Fault-tolerant; Unbalanced operation; Saturation; Fault-tolerance; Fractional slot; Permanent magnet synchronous machine; PMSM ; Concentrated windings;

   Abstract : 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. READ MORE

4. 2. Design and Evaluation of a Compact 15 kW PM Integral Motor

   Author : Peter Thelin; KTH; []
   Keywords : integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

   Abstract : 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. READ MORE

   Author : Peter Kjellqvist; KTH; []
   Keywords : active suspension; electromechanical actuator; permanent magnet synchronous machine; PMSM; rail vehicle; ride comfort;

   Abstract : .... READ MORE

6. 4. High Performance Cooling Traction Brushless Machine Design for Mass Production

   Author : Alessandro Acquaviva; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanentmagnet synchronous machine PMSM ; energy efficiency; Cooling; electrical machine design;

   Abstract : In the last few years electric vehicles (EVs) are coming on the market. The shift from niche market to main stream is challenging. It took many years to reach the current internal combustion engine quality in the manufacturing process. READ MORE

7. 5. Design and analysis of a fault-tolerant fractional slot PMSM for a vehicle application

   Author : Christian Dubar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saturation; Permanentmagnet synchronousmachine PMSM ; Fault-tolerance; windings; Concentrated; Fractional slot; Unbalanced operation;

   Abstract : The permanent magnet synchronous motor (PMSM) is an interesting alternative for an electric motor drive system in automotive applications, due to 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 a PMSM can achieve since it is very important to save especially space but also weight in vehicle applications. READ MORE
