Description
Technical field
The utility model belongs to the technical field of the motor manufacturing, and it is adjustable to particularly relate to a kind of hall position
Outer-rotor structure.
Background technology
Common external rotor electric machine Hall subassembly is fixed as shown in Figure 1, Hall subassembly is fixed by screws on drive end bearing bracket,
Hall position is unadjustable, the structure there are the problem of,（1）Motor Hall subassembly position is fixed, and can not be adjusted；（2）Even if PCB
Circuit board reserves kidney slot, and adjusting is also required to unclamp screw, and external rotor electric machine outer diameter is general and rotor diameter is suitable, it is difficult to reserve
Enough spaces adjust hall position from top pine screw；（3）The bad adjusting of Hall, since the factors such as technique/tolerance generate
Accumulated error, easily cause positive and negative rotation hall signal uniformity in waveform bad, motor can not operate under optimum condition, influence
Motor temperature rise and service life；（4）Even if vertical direction will remove rotor if capable of adjusting generally, repeated disassembled and assembled is easy to damage bearing,
And can not real-time testing hall signal, low production efficiency；Or can in a disguised form increase motor outer diameter, influence installation space.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of adjustable outer-rotor structure of hall position, Ke Yifang
Just hall position is adjusted in real time, ensures that motor positive and inverse signal is consistent.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The utility model is a kind of adjustable outer-rotor structure of hall position, including drive end bearing bracket, PCB circuit board and suddenly
You, is arranged retainer in the lower section of PCB circuit board, several positioning cylinders is provided on retainer, are also set up on retainer
It is jagged, it is additionally provided with several side screw holes on retainer, side corresponding with side screw hole is set on drive end bearing bracket
Face adjustment hole, retainer and PCB circuit board are fastened on by side adjustment hole and fixing screws on drive end bearing bracket.
Further improvement of the utility model is：Positioning cylinder is positioning cylinder made of plastic material.
The utility model has the beneficial effects that：（1）Increase PCB retainers, there is positioning column, side to have screw hole above, moulds
Expect that material, die sinking, the prices of raw materials are relatively low；（2）Hall PCB circuit board and retainer are positioned by cylinder, and glue bonds,
Hot pressure positioning cylinder etc. ensures bond strength；（3）Hall retainer and PCB circuit board one, are fastened on by the screw of side
On drive end bearing bracket；（4）When adjusting, side screw is unclamped, is rotated left and right, is adjusted in real time after confirming, it is fixed, you can to ensure motor operation
In optimum state, the utility model can easily adjust hall position in real time, ensure that motor positive and inverse signal is consistent；Motor begins
It is operated in optimum state eventually, reduces motor temperature rise, improve electrical machinery life；Motor outer diameter does not change.

Specific implementation mode
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
Detailed description, the embodiment are only used for explaining the utility model, do not constitute and limit to the scope of protection of the utility model.
As shown in Figs. 1-5, the utility model is a kind of adjustable outer-rotor structure of hall position, including drive end bearing bracket 1, PCB
Circuit board 2 and Hall 3 are arranged retainer 4 in the lower section of the PCB circuit board 2, are provided on the retainer 4 several
Positioning cylinder 5 is additionally provided with notch 9 on the retainer 4, accomplishes rationally to avoid, and Hall PCB and retainer are fixed by cylinder
Position, glue bond, and hot pressure positioning cylinder etc. ensures bond strength, several side screw holes are additionally provided on the retainer 4
6, side adjustment hole 7 corresponding with the side screw hole 6 is set on the drive end bearing bracket 1, and side adjustment hole 7 can pass through
Mold completes, and Hall retainer and PCB circuit board one, the retainer 4 and the PCB circuit board 2 pass through side
Adjustment hole 7 and fixing screws 8 are fastened on the drive end bearing bracket 1, and the positioning cylinder 5 is setting circle made of plastic material
Column, plastic material, die sinking/prices of raw materials are relatively low,
The cooperation of the retainer and PCB of the utility model can increase hot pressure point if PCB circumferential sizes are bigger,
With proof strength；Pay attention to the cooperation of retainer and drive end bearing bracket, should guarantee to be fixed with the screw of side, pays attention to keeping again
Frame can easily horizontally slip；Once being adjusted in place, screw position can be fixed with glue etc., increasing the IP etc. of motor
Grade.
The utility model is particularly suitable for external rotor electric machine, the high occasion of positive and negative rotation hall signal coherence request, especially
In the case that rotor magnetic steel tiltedly magnetizes, hall position adjusting is highly desirable.
