Design of a multi-power-terminals permanent magnet machine with magnetic field modulation

In this paper, a multi-power-terminals permanent magnet (PM) machine with magnetic field modulation is proposed. The advantage of this new integrated configuration includes not only the characters of permanent magnet synchronous motor (PMSM), but also the features of the no-contact transmission permanent magnet gear. Its topology and operation principle are introduced. Some techniques are employed to optimize and improve the motor performance, whilst validity of the proposed techniques is verified with finite element analysis (FEA).
