Abstract :
A novel E-core flux-switching PM (FSPM) brushless machine is proposed, and its electromagnetic performance is compared with that of the conventional FSPM brushless machine. The operation principle of the E-core FSPM machine will be firstly described and the influence of stator and rotor pole number combinations is investigated, while the electromagnetic performance of the optimized E-core FSPM machine is predicted by finite element analyses and validated by experiment. It is shown that the number and volume of magnets in the E-core FSPM machine is significantly reduced - only half of that in the conventional machine, while the phase back-emf and torque of the E-core machine are ~15% larger than those of the conventional machine.
