Motor cooling water channel structure

The utility model discloses a motor cooling water channel structure, which comprises a motor shell, a circulating water channel on the motor shell is axially processed from a water channel processing starting surface to a water channel processing ending surface, and the processed area forms an axial circulating water channel; a certain depth is axially processed on the water channel walls of the water channel processing starting surface and the plugging surface on the motor shell to form an annular circulating water channel; the plugging surface is provided with a plugging thread with a certain depth at the annular circulating water channel, and a bolt is installed in the plugging thread to form a sealing plug. The axial circulating water channels of the structure are of a non-penetrating type design structure, so that the machining time is shortened, the whole cutting output is reduced, the annular circulating water channels exist on the circle at intervals, the time increase caused by large-area machining i
