A flux-switching permanent-magnet (PM) (FSPM) machine is a new class of stator-PM brushless machines, which offers the advantages of high reliability, high power density, and high efficiency. In this paper, by employing redundant winding in the existing FSPM machine topology, a new redundant FSPM (R-FSPM) machine is proposed for a fault-tolerant operation of critical applications. The redundant winding...
This paper proposes a new 3-phase flux-switching permanent-magnet (FSPM) motor for fault-tolerant (FT) applications. The key is the new motor topology which incorporates the concept of FT teeth to provide the desired decoupling among phases. The proposed modular FSPM (M-FSPM) motor is quantitatively compared with the conventional FSPM motor. The analysis results show that the proposed M-FSPM motor...
The doubly salient permanent magnet (DSPM) motor is a new type of brushless machine and it offers advantages of high power density, wide speed range and simple structure. In this paper, a new drive topology for improvement of torque-ripple and fault-tolerance in an 8/6-pole DSPM motor is proposed. Based on co-simulation of magnetic and electrical circuit solvers, analysis of the proposed topology...
Flux-switching permanent magnet (FSPM) motor is a new brushless machine with magnets in the stator, offering the advantages of robust rotor structure, high power density and high efficiency. In this paper, a transient co-simulation method of coupled magnetic and electric circuit solvers is adopted for performance analysis of a FSPM motor drive. The magnetic circuit and the electric circuit are coupled...
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,...
