摘要： A stator for an electric machine has a circular stator body surrounding a rotor with an air gap therebetween. The stator has radially extending slots that define radially extending stator teeth. Multiple electric windings are located in the slots to define peripherally spaced magnetic poles. Separate coil groups establish multiple phases for the electric machine. Motor torque ripple is attenuated by forming the stator teeth with different widths for a given coil group.
