Abstract

Conventional surface mounted permanent magnet synchronous motor (SPMSM) at high speed has large iron loss in the stator and eddy current loss in the rotor. The higher the eddy current loss, the higher the rotor temperature. Therefore, a plan to reduce the loss must be devised. Also, weight at high speed is related to mechanical stiffness and electromagnetic vibration noise. Therefore, a plan to reduce the weight must be devised. In this paper, we propose to change the shape of the conventional 15 kW 110 000 rpm class into a slotless shape. A process of protocol change was proposed, and the sizing design of the rotor and stator was devised. The advantages of the proposed shape were verified through performance comparison through finite element analysis (FEA) and mechanical stiffness analysis.
