Testing system of new three-dimensional permanent magnet motor based on LabVIEW

Research and development of rare-earth permanent magnet machines;

Analysis on cogging torque in axial field flux-switching permanent magnet machine

A new hybrid excited doubly salient(HEDS)machine with a special magnetic bridge is presented,which combines the advantages of permanent magnet machines with the possibility of controllable magnetic flux by auxiliary DC field windings.

Voltage inputting for the rotor position estimation of a permanent magnet motor based on high-frequency signal injection;

Nonlinear Modeling and Simulation for Doubly Salient Permanent Magnet Motor with External Rotor Used in Electric Vehicle;

Analysis of 3D electromagnetic field in transverse flux permanent magnet motor;

A novel wide-range speed control for PM motor drive for electric vehicle;

Based on automatic generation technique of parametric mesh and directly discretization treatment of PM, a finite element analysis system for rare earth PM motor has been developed.

It can be foresaw that the study on PM motor will promote the development of marine electric propulsion in recent ten or twenty years.

Magnetic index of permanent magnetic motor should be calculated to find the feature of stabling and transient of the motor.
