Abstract:
Provided is a rotary electric machine including a rotor and a stator. The rotor includes a refrigerant passage. An axial direction of the rotor is along the horizontal direction. The stator is placed around the rotor and includes a tubular stator core. The stator core includes: a communication passage via which an inner peripheral surface of the stator core communicates with an outer peripheral surface of the tubular stator core such that the communication passage guides the refrigerant from the inner peripheral surface of the stator core to the outer peripheral surface of the stator core; and a projection portion provided on the outer peripheral surface of the tubular stator core such that the projection portion extends in the axial direction of the tubular stator core. The projection portion is placed downward in the gravitational direction from an opening of the communication passage on the outer peripheral surface.
