Abstract
This utility model relates to a kind of brshless DC motor with improvement main shaft, and it includes motor body, main shaft, counterweight iron block, balance weight and magnet steel；Wherein, described main shaft is supported on motor body by pair of bearings；Described counterweight iron block, balance weight and magnet steel are installed on main shaft successively, and are positioned at motor body；Described balance weight is specially the balance weight of aluminum matter, and it is drilled with some balance pipes.Of the present utility model have the brushless DC motor structure of improvement main shaft simply, and it is by arranging counterweight iron block, it is possible to makes the center of gravity of main shaft move to motor body, makes main axis steady；It is by arranging aluminum matter balance weight, and bores balance pipe on balance weight, so that the dynamic balance performance that this main shaft is when rotating is good, is not likely to produce circle and beats；The aluminum bits simultaneously boring balance pipe generation also will not be adsorbed by magnet steel.
Description
[technical field]
This utility model relates to a kind of motor, is specifically related to a kind of brshless DC motor with improvement main shaft, belongs to and spin
Machine part technical field.
[background technology]
Main shaft is the important component part of motor, and it is for the power of output motor.And if main shaft is positioned at outside motor
When part is longer, easily produces circle when it rotates and beat, normally use affecting user when beating serious；Meanwhile, prior art
Main shaft be usually irony, the iron filings produced during balance pipe thereon are easily adsorbed by magnet steel, thus affect the matter of motor
Amount.
Therefore, for solving above-mentioned technical problem, the brushless direct-current with improvement main shaft of a kind of innovation of necessary offer
Motor, to overcome described defect of the prior art.
[utility model content]
For solving the problems referred to above, the purpose of this utility model is to provide a kind of simple in construction, and dynamic balance performance is good, is difficult to
Produce the brshless DC motor with improvement main shaft that circle is beated.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of brushless direct-current with improvement main shaft
Motor, it includes motor body, main shaft, counterweight iron block, balance weight and magnet steel；Wherein, described main shaft is propped up by pair of bearings
Hold on motor body；Described counterweight iron block, balance weight and magnet steel are installed on main shaft successively, and are positioned at motor body；Institute
State balance weight and be specially the balance weight of aluminum matter, it is drilled with some balance pipes.
The brshless DC motor with improvement main shaft of the present utility model is further arranged to: one end of described main shaft is installed
There is a coding disk；Described motor body be provided with one and coding disk coordinate coding disk read head.
Compared with prior art, this utility model has the advantages that of the present utility model have improvement main shaft
Brushless DC motor structure is simple, and it is by arranging counterweight iron block, it is possible to makes the center of gravity of main shaft move to motor body, makes main shaft
Stability of rotation；It is by arranging aluminum matter balance weight, and bores balance pipe on balance weight, so that this main shaft moving when rotating is put down
Weighing apparatus performance is good, is not likely to produce circle and beats；The aluminum bits simultaneously boring balance pipe generation also will not be adsorbed by magnet steel.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the brshless DC motor with improvement main shaft of the present utility model.
[detailed description of the invention]
Refer to shown in Figure of description 1, this utility model be a kind of have improvement main shaft brshless DC motor, its by
Several parts compositions such as motor body 1, main shaft 2, counterweight iron block 3, balance weight 4 and magnet steel 5.
Wherein, described motor body 1 is prior art, does not repeats them here.
Described main shaft 2 is supported on motor body 1 by pair of bearings 6, and it can rotate and export power.Described main shaft 2
One end one coding disk 7 is installed；Described motor body 1 be provided with one and coding disk 7 coordinate coding disk read head 8, by compile
Code-disc read head 8 reads the positional information on coding disk 7, it is possible to control motor accurately.
Described counterweight iron block 3, balance weight 4 and magnet steel 5 are installed on main shaft 2 successively, and are positioned at motor body 1.Described
Balance weight 4 is specially the balance weight 4 of aluminum matter, and it is drilled with some balance pipes 9, and the position of balance pipe 9 is according to the needs balanced
Fixed.
The design principle of the brshless DC motor with improvement main shaft of the present utility model is as follows: by arranging counterweight iron block
3, it is possible to make the center of gravity of main shaft 2 move to motor body 1, make main shaft 2 stability of rotation；By arranging balance weight 4, it can also fill
When the effect of counterweight, and bore balance pipe 9 at balance weight 4, so that the dynamic balance performance that this main shaft 2 is when rotating is good, be difficult to produce
Raw circle is beated；The aluminum bits simultaneously boring balance pipe 9 generation also will not be adsorbed by magnet steel 5.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, all in this wound
Any modification, equivalent substitution and improvement etc. done within the spirit made and principle, should be included in this creation protection domain it
In.
Claims (2)
1. a brshless DC motor with improvement main shaft, it is characterised in that: include motor body, main shaft, counterweight iron block, put down
