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

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

    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. 4. Control of permanent-magnet synchronous machines in automotive applications

    Författare :Oskar Wallmark; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Eckart Nipp; KTH; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
