Establishment of a New Dual Rotor Flux Switching Motor Magnetic Circuit Model and Optimization of No-Load Back EMF

Abstract

A novel double rotor flux switching motor with a better output torque performance is proposed. The equivalent magnetic circuit model and the simplified equivalent magnetic circuit model of the motor are established, and the equations for calculating the main flux and the main flux density of the motor are derived. Finally, the Taguchi method is introduced into the optimization design of the dual rotor flux switching motor proposed in this article. A reasonable orthogonal test is designed. By comparison and analysis of the test results, it verifies that this optimization design can not only reduce the high-order harmonic content of no-load back electromotive force (EMF) but also improve the sinusoidal degree of no-load back EMF waveform.
