摘要：

This paper proposes a method of reducing ripple torque, i.e. the sum of cogging and commutation torques, in permanent magnet motors without skewing. The ripple torque for a given range of stator current can be substantially reduced by shifting the pole pairs by half a slot pitch and by choosing the value of magnet width so as to minimize the second-order component of cogging torque. The method is confirmed by the finite element analysis of permanent magnet motors with both radially magnetized and parallel magnetized magnets.
