MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/065586
Kind Code:
A1
Abstract:
Provided is a technique for improving the cooling performance of a motor comprising a core formed of a dust core. A motor 1 according to an embodiment of the present disclosure comprises: a stator core 211 formed of a dust core; an inserted member 24 disposed so as to oppose at least a part of a wall surface of the stator core 211 and capable of transmitting heat in an axial direction; a heat-dissipating member 40 configured to transmit heat from the inserted member 24 in the axial direction; and a fixing member 30 which fixes the stator core 211 and the inserted member 24. A stress produced between the stator core 211 and the inserted member 24 is smaller than a stress produced between the stator core 211 and the fixing member 30 and a stress produced between the inserted member 24 and the fixing member 30. The inserted member 24 and the stator core 211 are configured to transmit heat.
