Abstract
The utility model discloses a motor fan, which comprises a hub and fan blades which are fixedly arranged on the excircle surface of the hub, wherein the center line of each of the fan blades deviates from the center line of the hub. The supply air rate of the fan can be greatly improved through changing the angle of inclination of the blades under the condition of the same boundary dimension; and the motor fan can easily control the temperature rise of the motor, and has higher practical applicability.
Description
Technical field
The utility model relates to a kind of parts of motor, especially relates to the outside fan of a kind of motor.
Background technique
The fan of motor is a kind of motor component that is used for reducing electric machine temperature rise, and the axle head that it is fixed on machine shaft comprises wheel hub and flabellum, through wheel hub fan is fixed on the rotor axle head.The flabellum of prior motor external fan is perpendicular to the outer round surface of wheel hub, i.e. flabellum center line and wheel hub central lines, and the air output of the motor ventilating fan of this structure is less relatively, and is unfavorable for controlling motor and heats up, and has certain potential safety hazard.
The model utility content
The utility model provides the motor ventilating fan that a kind of air output is big, be easy to control the motor intensification in order to overcome the deficiency of existing technology.
To achieve these goals, the utility model adopts following technological scheme: motor ventilating fan comprises wheel hub and is fixedly arranged on the flabellum on the wheel hub outer round surface that the center line of said flabellum departs from the center line of wheel hub.
The utility model on the other hand, the center line of said fan sheet becomes 25 ° of angles with the center line of wheel hub.
The utility model is rational in infrastructure, through changing the flabellum angle of inclination, under the situation under the equal boundary dimension, can effectively increase the air output of fan, is easy to control electric machine temperature rise.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description.
As shown in Figure 1, motor ventilating fan comprises wheel hub 1 and is fixedly arranged on the flabellum 2 on wheel hub 1 outer round surface that the center line of flabellum 2 departs from the center line of wheel hub 1, and in the present embodiment, the center line of flabellum 2 becomes 25 ° of angles with the center line of wheel hub 1.Through changing the flabellum angle of inclination, under the situation under the equal boundary dimension, can effectively increase the air output of fan, be easy to control electric machine temperature rise.
Claims (2)
