Design and Testing of Low Pole Dual-Stator Flux-Switching Permanent Magnet Machine for Electric Vehicle Applications

This paper investigates the design and testing of a high-speed dual-stator 6/4 flux-switching permanent magnet (FSPM) machine. A dual-stator design is used to solve the issue of second harmonic presented in the flux linkage of conventional 6/4 FSPM machine. Different dual-stator designs are investigated and compared against each other in terms of the performance and manufacturability. Comparison between the proposed dual-stator 6/4 FPSM machine and a commonly seen 12/10 FSPM machine is done at 10 kW, 15000 rpm condition. Due to the 60% reduction of the fundamental frequency, a significant reduction in iron loss and magnet eddy current loss is observed, which leads to higher efficiency. A prototype dual-stator 6/4 FSPM motor is built and tested on a dynamometer set up to verify the analytical calculation and finite element analysis results. A comparison is made between measured data and simulation results, and good agreements are achieved.
