Abstract
The performance of the optimized conventional, novel E- and C-core flux-switching permanent magnet (FSPM) machines having different combination of stator and rotor pole numbers is compared by finite element analyses, with particular reference to the conductor and magnet eddy current loss and iron loss. Both iron loss and conductor eddy current loss increase with the rotor pole number, while the 11- and 13-rotor pole machine always exhibit lower magnet eddy current loss than those of the 10- and 14-rotor pole machine, respectively. The E- and C-core machines use half number and volume of magnets but exhibit higher efficiency than those of the conventional FSPM machine.
