Abstract :
A novel stator doubly fed doubly salient permanent magnet (PM) brushless machine is proposed. The novelty of this machine is to purposely add an extra flux path in shunt with each PM pole, hence amplifying the effect of flux weakening for constant power operation. Magnetic circuit analysis is adopted to illustrate the novelty. Machine flux paths and performance curves determined by a finite-element analysis are presented for various excitations. The corresponding results show that the proposed machine is promising for application to electric vehicles.
