The utility model provides a direct current brushless motor rotor when equipment, this clamp plate is pressed respectively on the magnet steel of both sides, and this two elastic arm supports and leans on on this clamp plate, and this screw passes this roof and clamp plate in proper order and finally screws in the fixed orifices on this mount, because the buffering of the elastic arm of this bolster and the secondary distribution of power, makes this mount that is fixed in that this magnet steel can stabilize, and can not damaged by pressure.
Description
Technical field
This utility model relates to DC Brushless Motor, particularly to a kind of DC Brushless Motor rotor.
Background technology
DC Brushless Motor is widely used in each technical field till now from being born, and Brushless DC motor includes
Rotor and stator.Common rotor includes rotating shaft, the fixed mount being sheathed in this rotating shaft, and it is solid to be located at this
Determine the some magnet steel on frame.
This fixed mount includes two parts: tightly fits in the core body in this rotating shaft, and is sheathed on this core body
Insulating support, this magnet steel is fixed on this insulating support, and in prior art, this insulating support is solid by screw
On this core body, and this magnet steel each also by some screws fix, this fixed form due to
The bad control of revolving force of screw, therefore often results in the damage of magnet steel.
Utility model content
Based on this, the technical problems to be solved in the utility model is to provide one and can prevent magnet steel in fastener cycle
The DC Brushless Motor rotor being subject to crushing.
A kind of DC Brushless Motor rotor, the fixed mount including rotating shaft, being sheathed in this rotating shaft and be fixed on this
Some magnet steel on fixed mount, farther include some fixtures, this fixture include pressing plate, bolster with
And a screw, this pressing plate is press respectively against on the magnet steel of both sides, and bolster includes a top board and from these top board both sides
Being folded down two elastic arms of extension, this top board and pressing plate are equipped with the through hole worn for screw, this is fixed
Frame is provided with the fixing hole being spirally connected for this screw between adjacent two magnet steel.
When DC Brushless Motor rotor in this utility model assembles, this pressing plate is press respectively against on the magnet steel of both sides,
This two elastic arm is resisted against on this pressing plate, and this screw sequentially passes through this top board and pressing plate and is finally tightened in this
In fixing hole on fixed mount, due to the buffering of elastic arm and the secondary distribution of power of this bolster, make this
What magnet steel can consolidate is fixed on this fixed mount, and will not be subject to crushing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the DC Brushless Motor rotor in this utility model first embodiment；
Fig. 2 is the partial structurtes enlarged drawing of DC Brushless Motor rotor in Fig. 1；
The partial structurtes enlarged drawing of the DC Brushless Motor rotor in Fig. 3 this utility model the second embodiment.
Detailed description of the invention
For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is carried out more comprehensively
Description.Accompanying drawing gives some embodiments of the present utility model.But, this utility model can be to be permitted
The most different forms realizes, however it is not limited to embodiment described herein.On the contrary, provide these to implement
The purpose of example is to make disclosure of the present utility model more thorough comprehensively.
Refer to Fig. 1, show the DC Brushless Motor rotor 100 in an embodiment of the present utility model, should
DC Brushless Motor rotor 100 includes rotating shaft 10, the fixed mount 20 being sheathed in this rotating shaft 10, is installed on
Some magnet steel 30 on this fixed mount 20 and the some fixtures 40 for mounting magnetic steel 30.
This fixed mount 20 is in column, and its periphery is provided with some draw-in grooves 21, forms edge between adjacent draw-in groove 21
Axially extended rib 22, each rib 22 is provided with two fixing holes 23.
This magnet steel 30 is in strip, and each magnet steel 30 is contained in the draw-in groove 21 on this fixed mount 20, often
A short slot 31 it is respectively equipped with on the dual-side of one magnet steel.Short slot on the relative limit of two adjacent magnet steel 30
31 is facing each other and lay respectively at the both sides of a rib 22.
Referring to Fig. 2, this fixture 40 includes pressing plate 41, bolster 42 and a screw 43, this pressing plate
In the short slot 31 of the magnet steel 30 that the two ends of 41 are press respectively against both sides, bolster 42 include a top board 421 and from
These top board 421 both sides are folded down two elastic arms 422 of extension, and this top board 421 and pressing plate 41 are equipped with
The through hole worn for screw 43.This elastic arm 422 is the most thinning to this pressing plate 41 from this top board 421, has
It is beneficial to elastic arm 422 and produces deformation near the end of magnet steel 30, protect institute's magnet steel 30.
When DC Brushless Motor rotor 100 in above-described embodiment assembles, this pressing plate 41 is press respectively against both sides
In the short slot 31 of magnet steel 30, this two elastic arm 422 is resisted against on this pressing plate 41, and this screw 43 sequentially passes through
This top board 421 and pressing plate 41 are also finally tightened in the fixing hole 23 on the rib 22 of this fixed mount 20.
Due to the buffering of elastic arm and the secondary distribution of power of this bolster 42, this magnet steel 30 is made to consolidate
It is fixed on this fixed mount 20, and will not be subject to crushing.
Refer to Fig. 3, the partial structurtes for the DC Brushless Motor rotor in this utility model the second embodiment are put
Big figure, the two ends of the pressing plate 41a of the fixture 40 in the present embodiment are provided with the hook part extended to this magnet steel 30
411, this hook portion 411 can firmly catch the magnet steel at two ends, and makes up due to pressing plate 41a and magnet steel 30
Contact area is less and fixing of causing does not moves solid problem.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that,
For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to
Making some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model
The protection domain of patent should be as the criterion with claims.
