Abstract
Disclosed is an external cooling type totally-closed DC machine, referring to the technical field of a DC machine, which comprises a machine body, a fan and a fan cover. The fan is arranged in the rear end of the machine body. The fan cover covers the fan and the machine body and is provided with an air vent. Between the fan cover and the machine body an air duct is arranged. Between the fan cover and the machine body a holder is arranged. The fan cover is fixed on the machine body by the holder. Due to the adoption of the arrangement, the temperature rise of the machine is reduced, the working efficiency is improved, the insulating reliability is increased and the useful life of the machine is prolonged.
Description
Technical field
The utility model 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.
The utility model content
In order to solve the problem basis of existing direct current machine radiating effect difference, utility model provides a kind of external cooling type totally-enclosed direct current motor.
The utility model comprises 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 utility model 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.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1, the motor main body, 2, fan, 3, fan housing, 4, ventilation hole, 5, the air channel, 6, support.
Embodiment
