Abstract
A motor includes a substantially cylinder-shaped motor yoke with an opening at one end, an end plate, and DC power input terminals. The end plate is positioned adjacent to the opening of the motor yoke, and the DC power input terminals are fixed to the end plate. The motor yoke has a grounding flange that protrudes from an outer periphery of the motor yoke adjacent to the opening. A negative terminal of the DC power input terminals has an elastic contact segment. The contact segment is pressed against the grounding flange to ground the motor yoke.
