摘要:
A frame included in an electric motor has an inflow hole that allows outside air to flow in an interior of the electric motor and an outflow hole that allows the outside air having flowed in to flow out of the electric motor. The electric motor includes a first partition member forming a first ventilation path between the first partition member and the frame, and a second partition member forming a second ventilation path between the second partition member and the frame. In addition, the stator has a third ventilation path penetrating through the stator from one end to another end of the stator in a direction of a rotational axis and configured to communicate with the first ventilation path and the second ventilation path.
