Energy-saving water-cooled motor

The utility model provides an energy-saving water-cooled motor, a water-cooled casing of the motor is provided with a communicating water channel, the communicating water channel is Z-shaped, the water-cooled casing is also provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively communicated with two ends of the communicating water channel. The communicating water channel comprises a plurality of axial water channels evenly distributed along the circumference and further comprises a plurality of water channels arranged along the circumference, the water channels are located at the two ends of the axial water channels, and the axial water channels are communicated end to end through the water channels. By adopting the scheme that the Z-shaped communication water channel is adopted, the temperature of the motor can be quickly taken away, and the cooling is uniform. And the structure of the axial water channel and the water tank is adopted, so that the processing
