  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

  3. 2. Main-circuit considerations of power coverters for integral motors

    Författare :Karsten Kretschmar; Hans-Peter Nee; Johan Walter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Permanent magnet integral motor; Small DC link; Elektronik; Electronics; Elektronik;

    Sammanfattning : This thesis deals with different converter topologies for a 15kW permanent magnet (PM) integral motor. An integral motor combines the motor and the power electronics in one unit. The main objective is to find suitable converter alternatives for an integral motor. LÄS MER

  4. 3. Integrated In-Wheel Motors for Low Power Traction Application

    Författare :Prakashraj Kasinathan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

    Sammanfattning : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. LÄS MER
