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

4. 2. On Control of Back-to-Back Converters and Sensorless Induction Machine Drives

   Author : Rolf Ottersten; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active filtering; flux estimation; sensorless control; induction motor; back-to-back converter; pulsewidth-modulated rectifier; virtual flux; vector current control;

   Abstract : This thesis focuses on design and analysis of the control system structure for back-to-back converter squirrel-cage induction machine drives. Particularly, sensorless control of induction machines, meaning vector control without a mechanical shaft sensor, and vector control of pulsewidth-modulated (PWM) rectifiers are considered.

6. 4. A permanent magnet synchronous motor for an electric vehicle - design analysis

   Author : Yung-Kang Chin; KTH; []
   Keywords : constant power speed range; electric vehicles; field-weakening; reference flux linkage;

   Abstract : This thesis presents the study and the design analysis of apermanent magnet synchronous motor (PMSM) for the tractionapplication of an electric vehicle. An existing inductiontraction motor for an electric forklift benchmarks the expectedperformances of the proposed PMSM design. READ MORE

7. 5. AFPM Motor/Generator Flywheel for Electric Power Stabilization

   Author : Juan de Santiago Ochoa; Uppsala universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The study of a motor/generator for flywheel energy storage, meant to smooth the power transients in a vehicular power train, is expounded in this licentiate thesis. The proposed motor/generator has two sets of windings in the stator, rated at different power and voltage levels, and a significant moment of inertia to store energy in the form of rotational kinetic energy.
