Abstract

The utility model discloses an internal air-cooled type direct-current motor. The internal air-cooled type direct-current motor comprises a housing, a front end cover which is installed at the front end of the housing, a rear end cover assembly which is arranged at the rear end of the housing, and a motor shaft which is arranged in the housing and supported between the front end cover and the rear end cover assembly. A rotor is fixed on the motor shaft, the inner wall of the housing is provided with a stator which is arranged in a manner that the rotor is surrounded by the stator, and a fan which is fixed on the motor shaft is arranged inside the housing at the inner wall side of the front end cover. According to the utility model, the fan for cooling is arranged inside the housing, so operating requirements in large power occasions can be satisfied without increasing the size of the motor, so that the fabricating cost is reduced.

Description

Interior air-cooled direct current machine
Technical field
The utility model relates to the motor technology field, especially a kind of interior air-cooled direct current machine.
Background technology
The direct current machine application is wider, use the occasion of relatively high power at some, can motor volume do larger, so that inside slips out enough spaces and is convenient to dissipation of heat, cause waste of material, cost improves, therefore be necessary meeting under the prerequisite of high-power instructions for use, both dwindle motor volume, had again radiating effect preferably, thereby do not affected the useful life of motor.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, providing a kind of is not increasing under the motor volume prerequisite, meets the interior air-cooled direct current machine of relatively high power instructions for use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of interior air-cooled direct current machine, comprise casing, be arranged on the casing front end front end housing, be located at casing rear end the rear end cap assembly, be located in casing and be supported in motor shaft between front end housing and rear end cap assembly, be fixed with rotor on motor shaft, casing inner wall is provided with the stator of surrounding rotor surrounding, is positioned at front end housing inwall side in described casing and is provided with the fan that is fixed on motor shaft.
The beneficial effects of the utility model are: the utility model is owing to being provided with the fan of cooling in casing inside, therefore can meet the instructions for use of relatively high power occasion in the situation that do not increase motor volume, reduced cost of manufacture.
Description of drawings
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of interior air-cooled direct current machine as shown in Figure 1, comprise casing 1, front end at casing 1 is provided with front end housing 2, casing 1 rear end is provided with the rear end cap assembly 3 with brush assembly of electric, motor shaft 4 is located in casing 1 and is supported between front end housing 2 and rear end cap assembly 3, be fixed with rotor 5 on motor shaft 4, casing 1 inwall is provided with the stator 6 of surrounding rotor 5 surroundings.
Be positioned at the space of front end housing 2 inwall sides at described casing 1, be provided with the fan 7 that is fixed on motor shaft 4, fan 7 synchronous rotation with the rotation of motor shaft 4 during work, thus the heat that produces while dispelling the work of power down machine has reduced the motor internal temperature preferably.
The utility model is owing to being provided with the fan 7 of cooling in casing 1 inside, therefore can meet the instructions for use of relatively high power occasion in the situation that do not increase motor volume, reduced cost of manufacture.
Above-mentioned execution mode only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the person skilled in the art can understand content of the present utility model and be implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
