Decrease torque ripple for SynRM using barrier arrangement design

Abstract

SynRM (Synchronous Reluctance Motor) is a high efficient motor with simple structure and lower price than induction motor. However, the torque ripple of Synchronous Reluctance Motor is very large. This paper analyzes the SynRM output characteristics with a new rotor flux barriers arrangement design. And the stator of SynRM is as similar as an induction motor. A method for reducing the torque ripple is described by designed the relative positions between outer edges of flux barriers and slots correspond. Then, devised several new models and compared with a basic model. As a result torque ripple can be reduced.
