2. 1. 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

5. 3. A Permanent Magnet Traction Motor for Electric Forklifts : Design and Iron Loss Analysis with Experimental Verifications

   Author : Yung-Kang Robert Chin; Chandur Sadarangani; Fabio Crescimbini; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Abstract : This thesis presents the design analysis of a permanent magnet synchronous motor (PMSM) for the traction application in electric forklifts. Within the scope of the study, an existing induction traction motor for electric forklifts benchmarks the expected performances of the proposed PMSM designs, as design specifications. READ MORE

6. 4. 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

7. 5. Permanent magnet motor drives with switched stator windings

   Author : Eckart Nipp; KTH; []
   Keywords : ;

   Abstract : Permanent magnet (PM) motors aretoday regarded as aninteresting solution for a wide range ofinverter-fedvariable-speed drives. The generally increasedinterest in these motors hasled to many investigations on theirfeasibility for vehicle propulsion. READ MORE
