A New Linear Fault-Tolerant Flux-Reversal Permanent-Magnet Machine

摘要：

　　This paper proposes a new linear fault-tolerant flux-reversal permanent-magnet machine for urban rail transit.The key of the proposed machine is that the magnetizer divides the short mover into two modules.As a result,the two modules of the short mover have the complementary magnetic circuit,and the detent force of the proposed machine is reduced.Also,it possesses more symmetrical and sinusoidal back electromotive force (back- EMF).In addition,the mutual inductances of the propose machine are much lower than the self inductances,hence offering fault-tolerant capability.The finite-element results confirm the validity of the proposed machine.
