Oil-cooled motor

The utility model discloses an oil-cooled motor, and aims to overcome the defect that an oil-cooled motor in the prior art can only carry out heat dissipation on the outside of a stator. The technical problem is solved through the following technical scheme: the inner wall of the motor shell is provided with a side wall oil duct; the rotating shaft is provided with a hollow cavity, and a first oil inlet hole communicating with the hollow cavity is formed in the side wall of the motor shell. A plurality of through holes are formed in the circumferential direction of the hollow cavity; the stator assembly is fixedly arranged on the inner side wall of the motor shell, and a front oil distribution ring and a rear oil distribution ring are arranged at the two ends of the stator assembly in the axial direction respectively; the front oil distribution ring, the rear oil distribution ring, the motor shell and the stator assembly form a sealed side wall cavity, and the front oil distribution ring is provided with an o
