Cooling water pump

Abstract

The design refers to the motor module and the cooling water pump with the motor module. The motor module has a first housing and a second housing combined; the drive shaft is assembled on the first housing and the second housing; the stator assembly is mounted in the first housing; and the rotor assembly is mounted on the drive shaft. The opening of the first housing creates the first assembly, which is easily assembled onto or removed from the second assembly of the second housing. The single-unit motor module can be assembled into the water pump through the housing opening, and then the motor cover is assembled on the housing opening, and the drive mechanism and housing can be assembled at the other end, making the assembly process easy.
