Abstract
A motor having multiple cooling flow channels, includes a housing, a stator, and a rotor. The stator comprises a winding. The housing comprises a cooling liquid inlet, an arc-shaped flow channel, and a cooling liquid outlet; the arc-shaped flow channel is defined around the housing and connected to the stator core; the rotor comprises a rotor flow channel; both the rotor flow channel and the arc-shaped flow channel are communicated with the cooling liquid inlet and outlet; and the rotor flow channel and the arc-shaped flow channel respectively correspond to two ends of the winding. A cooling liquid enters the arc-shaped flow channel for cooling the housing and a stator core of the motor, and enters the rotor flow channel for cooling the rotor. The cooling liquid flows through the rotor flow channel and the arc-shaped flow channel for respectively cooling the ends of the winding.
