This paper investigated a new type of operating mechanism in which the high voltage circuit breaker (HVCB) is driven by a permanent magnet synchronous motor (PMSM). This type of mechanism has high reliability due to its simple mechanical structure. In addition, the operating process of the mechanism is controllable. In this paper, the control technique of PMSM was introduced. A simulation model of...
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,...
The doubly salient permanent magnet (DSPM) motor is a novel type of AC brushless machine and it offers advantage of high power density, wide speed range and simple structure. To improve the reliability and fault-tolerant performance, a new dual-channel 12/8-pole DSPM motor speed-adjustable system is proposed in this paper. With the comprehensive introduction for the proposed redundant DSPM motor,...
