Abstract
Coolant flow channels include a main flow channel that is spaced apart from a magnet accommodating aperture on an inner circumferential side, and that passes axially through a rotor core; a magnet cooling flow channel that is formed on an inner circumferential side of a permanent magnet, an inner circumferential surface of the permanent magnet being a portion of the magnet cooling flow channel; and a relay flow channel that passes axially through the rotor core in a state in which the main flow channel and the magnet cooling flow channel are linked, a first end plate opens a first axial end of the main flow channel, and closes a first axial end of the magnet cooling flow channel and the relay flow channel, and a second end plate opens second axial ends of the main flow channel, the magnet cooling flow channel, and the relay flow channel.
