Performance optimization of synchronous reluctance machines with two rotor structures

The subject of this article is to optimize the design and compare the performances of synchronous reluctance machines with salient pole rotor and multi-flux barrier rotor. The optimization procedure, which focuses on the maximization of the machine's torque to Ampere ratio, is based on a cyclic algorithm coupled with the magnetostatic finite-element field solutions. The optimization results regarding the two types of machines which provide the optimized rotor geometrical dimensions and the influence of the current angle are discussed.
