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.
