Abstract

Purpose

The purpose of this paper is to propose a novel type of switched flux PM machines with two separate stators.

Design/methodology/approach

2D-FEA is employed to analyze the electromagnetic performance of the proposed machines. Moreover, the results are validated by experiments.

Findings

The proposed machine has higher torque density, less unbalanced magnetic force on the modulating steel piece and uses less PM volume.

Originality/value

The proposed machine is a low-cost novel topology with different rotor pole combinations.
