フーリエ級数を用いたIPMモータのトポロジー最適化

抄録

This paper proposes a topology optimization method for rotating machines, in which the rotor shape is represented in terms of the Fourier series. The rotor shape of an IPM motor is optimized to maximize the average torque and minimize radial torque variations using the present method. The proposed method is shown to provide the optimized rotors whose performances are comparable with those obtained by the NGnet-based method. The topology optimization performed by both methods can give useful information on the motor design.
