Description
Technical field
The utility model is related to DC motor technology field, more specifically to a kind of brushless noninductive direct current generator.
Background technology
The direct current generator used at present is mostly fixed by upper cover and the direct screw locking of iron ring, upper cover and iron ring junction
Because operational vibration will appear loosening, lead to unstable situation.
Utility model content
The technical problem to be solved by the present invention is to for the drawbacks described above of the prior art, provide a kind of brushless nothing
Feel direct current generator.
Technical solution is used by the utility model solves its technical problem：
A kind of brushless noninductive direct current generator of construction, including sequentially connected upper cover, iron ring and lower cover；Wherein, the upper cover
On be provided with the fixed annular flange of iron ring inner wall；It is provided on the flange and is uniformly distributed the multiple notches of setting, it is described
Permanent magnet is fixed in notch；Further include stator core, the coil being wrapped on the stator core and with the stator core
Fixed axis branch；The lower cover two sides are both provided with the bearing for installing the axis branch.
Brushless noninductive direct current generator described in the utility model, wherein, the axis branch passes through axis branch with the stator core
Frame is fixedly connected.
Brushless noninductive direct current generator described in the utility model, wherein, the iron ring outer surface is provided with radiating groove.
Brushless noninductive direct current generator described in the utility model, wherein, the radiating groove be annular groove, and with the iron ring
Coaxial arrangement.
Brushless noninductive direct current generator described in the utility model, wherein, the radiating groove is set in the iron ring outer surface
Have multiple, and multiple radiating grooves are mutually parallel or are staggered.
The beneficial effects of the utility model are：Flange is set to stretch into iron ring inner wall on during installation on lid to be fixed, is made
It obtains and heat transfer that is more firm, while being convenient for iron ring internal heat is connected between upper cover and iron ring, improve radiating efficiency；By convex
Set notch that permanent magnet to be installed on edge, when assembling is more convenient.
Description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below in conjunction with attached drawing and reality
Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only the section Example of the present invention, for this
For the those of ordinary skill of field, without creative efforts, it is attached to can also be obtained according to these attached drawings other
Figure：
Fig. 1 is the brushless noninductive direct current generator explosive view of the utility model preferred embodiment.
Specific embodiment
In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, below in conjunction with this practicality
Technical solution in new embodiment carries out clear, complete description, it is clear that described embodiment is the portion of the utility model
Divide embodiment rather than whole embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not paying creation
Property labour under the premise of all other embodiments obtained, belong to the scope of protection of the utility model.
The brushless noninductive direct current generator of the utility model preferred embodiment as shown in Figure 1, including sequentially connected upper cover 1,
Iron ring 2 and lower cover 3；The fixed annular flange 10 of 2 inner wall of iron ring is provided in upper cover 1；It is provided with to be uniformly distributed on flange 10 and set
Multiple notches 100 are put, permanent magnet 20 is fixed in notch 100；Further include stator core 4, the coil being wrapped on stator core 4
5 and with 4 fixed axis branch 6 of stator core；3 two sides of lower cover are both provided with the bearing 30 of installation axle branch 6；During installation in upper cover 1
Setting flange 10 stretches into 2 inner wall of iron ring and is fixed so that it is more firm to be connected between upper cover 1 and iron ring 2, while convenient for iron ring
The heat transfer of 2 internal heats improves radiating efficiency；By notch 100 being set to install permanent magnet 20 on flange 10, assemble
When it is more convenient.
As shown in Figure 1, axis branch 6 is fixedly connected with stator core 4 by axis branch frame 60；Connective stability is good, convenient for assembling.
As shown in Figure 1,2 outer surface of iron ring is provided with radiating groove 21；Radiating efficiency is improved, while mitigates overall weight.
As shown in Figure 1, radiating groove 21 is annular groove, and it is coaxially disposed with iron ring 2；Improve radiating efficiency.
As shown in Figure 1, radiating groove 21 is provided with multiple in 2 outer surface of iron ring, and multiple radiating grooves 21 are mutually parallel or hand over
Mistake setting；Improve radiating efficiency；It is additionally beneficial to ensure 2 intensity of iron ring when being staggered.
It should be understood that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
