Description

Technical Field

[0001] The utility model relates to the technical field of motor accessories, in particular to a ventilation structure of a steel plate shell water pump motor. Background Art

[0002] Water pump motors are classified into horizontal motors and vertical motors according to their structure. Since the working characteristics of water pumps are relatively small starting torque, relatively low starting frequency, and relatively long continuous operation time, most water pump motors are squirrel cage rotor asynchronous motors or synchronous motors.

[0003] The water pump motor will generate heat when working. If good ventilation and heat dissipation cannot be achieved, the normal use of the water pump motor will be affected. Utility Model Content
