In terms ofatures andexcitation, reluctance motors can be classified into switchedmotors and synchronous reluctance motors. With the rapid solidstate power converters and the corresponding increasing ofratio of reluctance motors, it appears that substantialbe madein the performance of reluctance motors and their potentialapplication in variable speed drives. This thesis is to studycontrol characteristics of high performance reluctance motors.A nonlinear magneto static finite element method is used forisand performance calculation. A comparison between theDCbrushless motor (SANYO BL-868), switched reluctance motor andreluctance motor in the same yoke frame and rotor diameter isAn experimental synchronous reluctance motor based on thenmethodology has also been fabricated for feasibility study andoperation. With the same linear current density, the switchedrhas the the highest output torque and it is better than the DC.The synchronous reluctance motor has the lowest output torque.ratio for the experimental synchronous reluctance motor is6.25. torque for the experimental synchronous reluctance motoris about of the DC brushless motor.
