Double-shaft-extension high-speed water-cooled motor

The utility model discloses a double-shaft-extension high-speed water-cooled motor, which belongs to the technical field of motor heat dissipation and comprises a three-phase permanent magnet synchronous motor body with two extension shafts, a sealing ring and an outer shell are sequentially distributed on the outer side of the body, and an opening type groove which is spirally distributed along the inner wall of the outer shell is formed in the outer shell. The sealing ring is inserted into the outer shell to seal the groove to form a spiral water channel, and a water inlet and a water outlet are formed in the two sides of the spiral water channel respectively. According to the water-cooled motor in the embodiment, when the water-cooled motor is not used or needs to be maintained, the sealing ring can be taken out from the inner wall of the outer shell in a detachable mode, and at the moment, a brush or other cleaning tools extend into the groove through the opening to clean the inner wall of the groove, so
