Motor with multiple bus rings
First Claim
1. A motor comprising:
- a stator including a plurality of motor coils;
a plurality of bus rings configured to distribute currents of a plurality of different phases to the motor coils; and
a ring-shaped bus ring holder in which a plurality of holding grooves configured to hold the respective bus rings are formed,wherein each of the motor coils includes an insulator around which a wound wire is wound,the insulator includes an outer flange formed at an outer side of the wound wire in a radial direction of the motor and extending in an axial direction of the motor, andthe bus ring holder is arranged at an outer side of the outer flange in the radial direction of the motor, and contiguous to the outer flange.
