Abstract

Disclosed is a front fan for a motor. As motor types increase, existing fans for motors cannot meet needs of certain motors; if conventional fans are used on certain special motors, air power generated by the fans are weak, and heat generated when the motors run cannot be timely lowered, so that service lives of the motors are influenced. Consequently, the front fan generates vortex air in the process of rotating and is large in air power.

Description

A kind of front fan of motor
Technical field
The present invention relates to a kind of fan of motor, to be especially a kind ofly used on motor and the fan of eddy current shape wind can be produced.
Background technique
At present, the structure of the fan blade that known motor uses is mainly with the structure of cambered surface and the structure of bending, the wind-force that the process fan of the use of this fan produces is not very large, along with the increase of motor type, the fan of existing motor can not meet the needs of some motors, if be arranged on some special motors by traditional fan, the wind-force that fan produces is more weak, the heat produced when can not reduce motor rotation timely, will affect the working life of motor like this.
Summary of the invention
Can not meet the heat radiation needs of some motors in order to overcome existing fan, the invention provides a kind of novel fan, this fan can produce larger eddy current wind in use, and wind-force is larger, can meet the heat radiation needs of some motors.
The technical solution adopted for the present invention to solve the technical problems is: have a big hole at the middle part of the fan be made up of metallic material, circular hole surrounding have 4 for the aperture of fan attachment, the outer circumferential edge of fan has the blade of multiple upwards bending, the middle part of the blade of bending is again through bending, by the structure of this bending, fan can be made in the process of rotating to produce eddy current wind, and wind-force is larger.
The invention has the beneficial effects as follows, fan can be allowed to produce eddy current wind, and the wind-force that fan produces is also larger.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural drawing of the present invention.
1. big holes, 2. aperture, 3. blade, 4. blade bottom, 5. bending line, 6. vane nose, 7. blade in figure.
Embodiment
In FIG, big hole 1 is positioned at the center of fan, during installation, the steel axle of rotor can pass from big hole, there are aperture 2 and other 3 apertures in the surrounding of big hole 1, the effect of aperture is two ends fan being fixed on rotor, blade bottom 4 place carries out bending to the direction of blade 7, and vane nose 6 sentences bending line 5 to the certain angle of the direction bending of blade 7, is fixed in the bottom of fan and one end of rotor during use.

Claims (2)

1. the front fan of a motor, a big hole is had at the middle part of the fan be made up of metallic material, circular hole surrounding have 4 for the aperture of fan attachment, the outer circumferential edge of fan has the blade of multiple upwards bending, and the middle part of the blade of bending is again through bending.
2. the front fan of a kind of motor according to claim 1, is characterized in that: the quantity of the blade on fan is 12.
