Abstract
A stator includes multiple motor coils. The motor coils include multiple U-phase coils, multiple V-phase coils and multiple W-phase coils which are arranged in a circumferential direction of a motor. A neutral bus ring connects the motor coils together. The neutral bus ring is divided into multiple bus ring members. Each bus ring member connects together any one of the U-phase coils, any one of the V-phase coils and any one of the W-phase coils.
