MOTOR

PROBLEM TO BE SOLVED: To provide a configuration which can sufficiently cool a motor.SOLUTION: A refrigerant flowing path 36 for flowing a cooling medium is formed at an outer peripheral side of the rotor 30 so as to communicate axial-direction endpoints 30a, 30b of a rotor 30. The refrigerant flowing path 36 is formed so as to incline and have a larger cross section toward the endpoints 30a, 30b in a rotational direction from a region 37c of an axial-direction central part of the rotor 30, and the region 37c of the central part is formed so as to be covered at an outer peripheral side and positioned at a radial-direction outside of a permanent magnet 34. From above configuration, a motor 20 can be sufficiently cooled.
