摘要

A fault-tolerant permanent-magnet vernier (FT-PMV) machine incorporates the merits of high fault-tolerant capability and high torque density. In this paper, a remedial phase-angle control (RPAC) strategy is proposed for a five-phase FT-PMV machine with short-circuit fault. Firstly, the proposed strategy can reduce the amount of unknown quantities by structuring the phase-angles of the normal phases. It can simplify the calculation of the remedial currents. Then, in order to obtain the desired torque, only the amplitudes of the remedial currents need to be calculated. Based on the principle of instantaneous electrical input power and mechanical output power balance condition, the real components are used to maintain the torque capability, while the reactive components are limited zero to minimize the torque ripple. Both simulations and experiments are presented to verify the proposed RPAC strategy.
