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.
