摘要
A new double-sided linear flux-switching permanent magnet (DSLFSPM) motor with a yokeless mover is proposed in this paper. First, the topology and structure of the proposed motor are presented, and the pole pitch ratio and segment number are shown to strongly affect performance. Second, the electromagnetic performance of DSLFSPM motors with a secondary yoke and without a secondary yoke are compared and described. Third, according to analytical models, air-gap flux-density levels and corresponding harmonics are investigated, and force production mechanisms of the proposed motor are presented. The analytical results match to the FEA results. Finally, experiments on a prototype are carried out to validate the simulation results. Back EMF, cogging force, and inductance values of the prototypes are measured and experimental results for the drive systems are presented.
