Rotor Design and Performances of a Multi-Flux Barrier Synchronous Reluctance Motor

Abstract

It is demonstrated that the rotor design of multi-flux barrier synchronous reluctance motors can be optimized in terms of a key geometric parameters, i.e., the optimum number of flux barrier and the ratio of the flux barrier width to the iron rib width so as to obtain maximum torque production. The results indicate the 6-layer flux-barrier rotor is optimum design considering practical use. An experimental motor has been fabricated and the results of measurements of the motor parameters prove the validity of the rotor design optimization.
