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

   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

5. 3. Control of permanent-magnet synchronous machines in automotive applications

   Author : Oskar Wallmark; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; electric vehicle; fault tolerance; hybrid electric vehicle; inverter; in-wheel motor; loss minimization; permanent-magnet synchronous machine; phase-locked loop; position estimation; sensorless control; vector control;

   Abstract : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotive applications. Sensorless control, meaning vector control without a mechanical rotor position sensor, is considered and a speed and position estimator of phase-locked loop type is analyzed thoroughly. READ MORE
