Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motors, in particular to a motor with a cooling function. Background Art
[0002] Motors are devices that convert electrical energy into mechanical energy and are widely used in manufacturing in various industries. Motors are also used in ammonia furnaces, but the temperature in ammonia furnaces is very high and there is ammonia. Conventional motors are only sealed with rubber rings. In high temperature environments, rubber rings are prone to aging, resulting in a decrease in the sealing effect of rubber rings. Ammonia will also enter the motor and corrode the motor, shortening the life of the motor. Utility Model Content
