Abstract

The impact of machine geometry on the performance of double-stator synchronous permanent magnet (PM) machine having different rotor pole numbers is investigated in this paper. The considered design parameters include: the split-ratio, rotor radial thickness, stator back-iron thickness, and rotor inner and outer radial lengths. It is observed that, there are optimum values for each of the design elements due to the changing condition of the electromagnetic reaction. Comprehensive analysis of the effects of the above mentioned design parameters on the fundamental back-electromotive force (EMF) and losses are given. The analysis shows that the 7-rotor pole machine has the best efficiency as well as the largest fundamental EMF value. It is also observed that, the least PM eddy current loss in addition to least overall core loss of the machine is seen in the 5-rotor pole machine.
