Abstract
An electric motor includes a shaft that is rotatably supported for rotation around a rotation axis, a rotor that is located outwardly of the shaft in a radial direction and rotates integrally with the shaft, a stator that faces the rotor in the radial direction, and a tubular frame that has an inner peripheral surface to which the stator is fixed. The electric motor further includes a groove included in (i) the inner peripheral surface of the frame or (ii) an outer peripheral surface of the stator, and an insulating member disposed in the groove.
