Patent ID: 7663287

Claim:
A motor comprising: a stator including: a stator core including a core back having a substantially circular shape centered on a center axis, and a plurality of tooth portions extending radially inwardly from the core back and arranged in a circumferentially spaced manner; an insulator covering at least a portion of the stator core so as to insulate at least the portion of the stator core; and a coil defined by a multilayer structure of a wire wound around each of the tooth portions via the insulator; and a bus bar arranged axially above the stator and including: a conductor plate having a plurality of terminals arranged to be connected to an end portion of the wire, and a plate support supporting the conductor plate and having an axially lower surface, a portion of the plate support faces the coil via a space defined therebetween; wherein the wire includes a crossover wire portion and the wire extracted from the coil extends in the circumferential direction at the crossover wire portion; an axial height of the space defined between the portion of the lower surface of the plate support and the coil is greater than a diameter of the wire; and a portion of the insulator, which is located radially inside relative to the coil, axially faces the axially lower surface of the plate support via a gap defined therebetween, and an axial height of the gap is smaller than a diameter of the wire.
