This paper proposes a novel multistep design and optimization strategy to minimize torque pulsations in a spoke-type permanent magnet motor with phase-group concentrated-coil windings. Different from the conventional techniques that work on the motor itself, in the first step, an auxiliary inner stator is designed to suppress torque pulsations with the aid of a finite-element method (FEM). In the...
This paper proposes a multi-step design and optimization strategy to minimize torque pulsations in a spoke-type PM motor with phase-group concentrated-coil windings. Different from the conventional techniques that work on the motor itself, in the first step (interim model I), an auxiliary inner stator is adopted to suppress the torque pulsations. In the second step (interim model II), the optimization...
