Engine equipment

Abstract

The invention relates to a motor device capable of reliably shielding the motor from heat and providing insulation protection. The motor device 1 comprises: a stator 10 around which winding 33 is wound; a rotor 11 arranged to rotate relative to the stator 10; a motor housing 14 containing the stator 10 and rotor 11; a bearing 22R supporting the rotating shaft 12 of rotor 11 in a way that allows it to rotate; a bearing housing 19 holding bearing 22R; a base 17 arranged at one end on the opposite side of the stator 10, with the bearing housing 19 of motor housing 14 clamped in between, and performing rotational control of rotor 11; The heat shield 18 is positioned between the bearing housing 19 and the base 17 and prevents heat generated in the motor housing 14 from transferring to the base 17. The bearing housing 19 has a hole 53 for the conductor connector 51 to be inserted, and the inner surface of the hole 53 is covered by the heat shield 18.
