Fault-tolerant flux-switching permanent magnet (FT-FSPM) motor is a new class of stator-PM brushless motors, a potential candidate for many applications where reliability and power density are of importance. In this paper, a new method is proposed for torque ripple minimization, in which the key is to introduce harmonic currents to compensate for non-ideal sinusoidal back-EMF. Moreover, a fault-tolerant...
The redundant flux-switching permanent-magnet (R-FSPM) motor is a new class of stator-PM brushless machines with redundancy, incorporating the merits of simple rotor structure, high reliability and high power density. Firstly, its structure characteristic and electromagnetic performance is investigated. Secondly, in order to operate the R-FSPM motor in single-channel (SC) mode for post-fault operation,...
This paper develops the concept of employing the redundant winding in a flux-switching permanent magnet (FSPM) machine. A new redundant FSPM machine is proposed for fault tolerant operation of critical applications. The redundant winding configuration is analyzed and the corresponding suitable control strategy for the post-fault is proposed. The electromagnetic performance of the redundant FSPM machine...
