Description

technical field

[0001] The invention belongs to the technical field of water pumps, in particular to a motor used for water pumps. Background technique

[0002] At present, most of the existing ordinary oil-immersed motors have excellent sealing performance, but the problem that follows is that the heat dissipation performance inside the fuselage is very poor. For some hot weather areas, these water pump motors are often due to the The internal heat dissipates, causing the internal temperature of the fuselage to be too high, and the normal operation of the fuselage is seriously affected. The service life of the water pump motor is also very short, and if there is oil leakage, it will seriously affect the ecological environment. Contents of the invention

[0003] The object of the present invention is to provide a motor for water pumps with stable structure, good heat dissipation effect and environmental protection.

[0004] The object of the present invention is achieved ...
