Liquid cooling motor

A liquid-cooled motor disclosed by the present invention comprises a motor shell, a liquid inlet pipe, a liquid outlet pipe and a stator core arranged in the motor shell, the stator core is internally provided with a first cooling liquid flow channel along the circumferential direction and a plurality of second cooling liquid flow channels along the axial direction, the multiple second cooling liquid flow channels are distributed in the circumferential direction and communicate with the first cooling liquid flow channel, the liquid inlet pipe communicates with the first cooling liquid flow channel, and the liquid outlet pipe communicates with the interior of the motor shell. Cooling liquid enters the stator iron core in the motor shell from the liquid inlet pipe, then cools the stator iron core through the first cooling liquid flow channel and the second cooling liquid flow channel, and then is sprayed to the stator winding from the two ends of the second cooling liquid flow channel to take away heat of the s
