Optimum Shape Design of Spoke Type Motor for Maximum Torque and Minimum Torque Ripple

Spoke type 전동기의 최대토크와 최소토크리플을 위한 형상 최적 설계

In this paper, we investigate the optimization design for a spoke type motor with the characteristics of high torque density and high-efficiency. This motor has a high output per unit volume. In order to reduce noise and vibration caused by a high cogging torque, optimization design of the rotor and stator have been conducted using both Response surface method (RSM) and Finite elements method (FEM). In this paper, we show the potential for this motor to efficiently replace existing interior permanent magnet synchronous motors (IPMSM) in a wide range of industries.
