Comparison of Linear Switched Flux Permanent Magnet Machines

Abstract:

This paper proposes a linear sandwiched switched flux permanent magnet (LSSFPM) machine and two double-sided linear switched flux permanent magnet (LSFPM) machines havingtoroidal windings. Bothmachines are optimized and then compared with the conventional 6-slot/5-pole LSFPM machine. It is found that the proposed machines exhibithigher magnet usage efficiencies than the conventional LSFPM machine, and the double-sided machines show shorter end-windings, which are benefited from toroidal windings. The performance, including back-EMF, cogging force and average thrust force, are analyzedby two-dimensional (2-D) finite element analysis (FEA).
