Abstract:
Provided is a motor including a rotor, a stator having a stator core and a coil, a stator frame, an end cover, first and second bearings, and a heat radiating resin in the stator frame. The coil includes first and second end portions projecting oppositely and axially. The stator frame includes a peripheral wall and an end wall, whose respective central parts form first and second boss portions holding the first and second bearings respectively. The heat radiating resin includes a first resin part covering the first end portion and closely contacting an inner surface of the stator frame, and a second resin part covering the second end portion and separating from an outer peripheral surface of the second boss portion. The first resin part has a portion between the first end portion and the first boss portion, the portion having a greater thickness than that of the other.
