A motor includes: a motor housing, a stator core, a stator winding, and a rotor core, the stator core mounted in the motor housing, the stator winding wound around the stator core, the rotor core rotatably disposed with respect to the stator core, the rotor core having a rotor flow path to transport coolant to the stator winding, a stator flow path disposed in the motor and in communication with the stator winding; and a valve configured to control a flow of the rotor flow path. The rotor core includes a rotor flow channel inside. The motor includes a magnetic shield having a magnetic shield flow channel inside. A first end of the magnetic shield flow channel is configured to guide the coolant to the stator winding, and a second end of the magnetic shield flow channel is in communication with the rotor flow channel.
