Electromagnetic performance of switched flux PM machines with two separate stators.

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. [ABSTRACT FROM AUTHOR]
