Abstract
The invention relates to an external cooling type totally-enclosed direct current motor, belonging to the technical field of a direct current motor. The external cooling type totally-enclosed direct current motor comprises a main body of the motor, a fan and an exhaust hood, wherein the fan is arranged at the back end of the main body of the motor; the exhaust hood is covered on the fan and the main body of the motor; ventilation holes are formed on the exhaust hood; an air duct is arranged between the exhaust hood and the main body of the motor; a bracket is arranged between the exhaust hood and the main body of the motor; and the exhaust hood is fixed on the main body of the motor through the bracket. The arrangement lowers the temperature rise of the motor, improves the working efficiency, increases the insulation reliability and prolongs the service life of the motor.
Description
Technical field
The present invention relates to a kind of technical field of direct current machine.
Background technology
The totally-enclosed DC motor of existing ZBL4 is made power and is generally 15KW, and its type of cooling is that inside carries fan, and cooling air cools off at inner Venus, along with the temperature rise of motor uprises, cooling air also can temperature also can uprise the cooling effect variation.
Summary of the invention
In order to solve the problem basis of existing direct current machine radiating effect difference, invention provides a kind of external cooling type totally-enclosed direct current motor.
The present invention includes motor main body, fan, fan housing, described fan is arranged in the rear end of described motor main body, described fan housing covers on described fan and the motor main body, on described fan housing, ventilation hole is set, between described fan housing and motor main body, the air channel is set, between described fan housing and motor main body support is set, described fan housing is fixed on the motor main body by support.
The present invention is arranged on fan the outside of motor, fan housing integral body is covered outside the described motor fuselage, cooling air all flows in the air channel of motor main body and fan housing formation, because of the cooling air by the air channel is new cooling air, the temperature of himself can not raise along with the temperature rise of motor, above-mentioned the temperature rise that has reduced motor is set, and has improved operating efficiency, the insulating reliability that increases, the useful life of the motor of raising.
