摘要： A technique that improves cooling performance of a motor including an iron core formed of a powder magnetic core is provided. A motor 1 according to one embodiment of the present disclosure includes a stator iron core 211 formed of a powder magnetic core and an inserting member 24 disposed so as to face at least a portion of a wall surface of the stator iron core 211, the inserting member being configured to enable heat to be transferred in an axial direction. The motor 1 includes a heat dissipation member 40 configured to enable the heat from the inserting member 24 to be transferred in the axial direction. The motor 1 includes a fixing member 30 that fixes the iron core 211 and the inserting member 24. Stress generated between the stator iron core 211 and the inserting member 24 is less than each of stress generated between the stator iron core 211 and the fixing member 30, and stress generated between the inserting member 24 and the fixing member 30. Each of the inserting member 24 and the stator iron core 211 is configured to enable the heat to be transferred.
