摘要:
A motor includes: a stator; a rotor axially aligned with the stator; a circuit board; and a heat dissipating plate. The stator includes: an iron core including teeth; an insulator covering one end surface, in the axial direction, of the iron core; and a coil wound around the teeth. The insulator includes an electrically insulating material having a lower rate of heat transfer than a material included in the iron core. The heat dissipating plate is attached to the insulator in a state in which the heat dissipating plate is in contact with the insulator without being in contact with the iron core, and the circuit board is attached to the heat dissipating plate in a state in which the circuit board is in contact with the heat dissipating plate without being in contact with the iron core.
