Abstract

The rotor structure of a synchronous reluctance machine (SynRM) engages some design complexities. These complexities have made it impossible to employ a generalized design method valid for all machine topologies with various number of rotor and stator slots till now. However, using trial and error and optimization algorithms such as genetic algorithms, etc., an optimal design is obtained which is both time consuming and complicated. Indeed, high amount of ripple in the developed torque is a serious problem of SynRMs, which could be reduced by employing an effective design method. This paper presents a new SynRM rotor analytical design method with the aim of reducing torque ripple while maintaining average torque. To this end, the proposed method is applied to a SynRM with 24 stator slots and 2, 3, and 4 rotor flux barriers. In order to evaluate the proposed method’s effectiveness, three designed SynRMs’ electromagnetic performances are simulated using finite elements method (FEM). It has been shown that the design parameters resulted by the proposed analytical method is close to the optimal state obtained by preceding time-consuming complicated methods.
