Abstract:
A frame of an electric motor has inlet holes to allow ambient air to flow into an inside of the motor and outlet holes to allow the ambient air entering through the inlet holes to flow out to an outside of the motor. The motor includes a shaft, a rotor, a stator, a fan to rotate integrally with the shaft, and a guide. The guide is disposed outwardly of the fan in the radial direction and has a shape for suppressing foreign materials contained in the ambient air entering through the inlet holes from coming into contact with the stator and the rotor.
