Design and performance analysis of permanent magnet flux-switching motors using segmental permanent magnets

抄録

This paper proposes a structure of permanent magnet flux-switching motors (PMFSM) using “mixed” segmental permanent magnets, which is based on analysis of the structure and the operational principle of PMFSM. The paper researches the influence of tangential and radial segmental permanent magnets on motor’s electromagnetic torque, torque ripple and cogging torque respectively, which is based on the finite element analysis of a 12/10 three phase permanent magnet flux-switching motor. The research shows that the motors using this new structure can reduce torque ripple and cogging torque by comparing with the conventional permanent magnet flux-switching motor, and the motors have negligible influence on the other performances, such as the flux linkage and the induced voltage.
