Rotor 100 below with reference to Fig. 1-Fig. 2 descriptions according to the utility model embodiment.
It can be included according to the rotor 100 of the utility model embodiment：Rotor core 1, rotating shaft 2 and magnet steel 3.
As shown in figure 1, being provided with magnet steel groove 11 on rotor core 1, and it is additionally provided with repeated hole 12, matches somebody with somebody on rotor core 1
Repeated hole 12 includes：First matches somebody with somebody repeated hole 122 with repeated hole 121 and second, and the sectional area of the first cross section with repeated hole 121 is more than second
The sectional area of cross section with repeated hole 122.First is suitable to carry out matching somebody with somebody reconnection with counterweight pin with repeated hole 121 and second with repeated hole 122
Connect, make the weight of rotor core 1 uniform, avoid because of the motor oscillating caused by the weight inequality of rotor core 1 the problems such as.
Rotating shaft 2 wears rotor core 1 and fixed with rotor core 1.Rotor core 1 is rotated centered on rotating shaft 2.
Magnet steel 3 is arranged in magnet steel groove 11.The volume and again of motor can be greatly reduced compared with ordinary sinter magnet using magnet steel 3
Amount.
According to the rotor 100 of the utility model embodiment, the rotor 100 on rotor core 1 by setting
First aggravate regulation amount of unbalance with repeated hole 121 and second with repeated hole 122, to meet regulatory demand, reaches easy assembling,
Production hour is saved, reduces the effect of processing cost.And with repeated hole without later stage perforate, therefore fundamentally solve the later stage and open
Chip caused by hole pollutes.
Further, first connected with repeated hole 121 with second with repeated hole 122.Thus, it is easy to machine-shaping.
Reference picture 1, first matches somebody with somebody repeated hole 122 with being arranged to multiple second around repeated hole 121, and each first matches somebody with somebody repeated hole
121 connect with multiple the second of surrounding with repeated hole 122.
According to some embodiments of the utility model, each first matches somebody with somebody the edge of repeated hole 122 with multiple second around repeated hole 121
First matches somebody with somebody the circumferential equidistantly distributed of repeated hole 121.Thus, the uniform force everywhere of rotor core 1 can be made, make first to match somebody with somebody repeated hole 121
With second with repeated hole 122 be suitable to counterweight pin carry out with reconnection become quantify, it is controllable, avoid because of the unbalance stress of rotor core 1
Caused oscillation phenomenon.
Each first matches somebody with somebody repeated hole 121 and multiple the second of surrounding forms a set of weights aperture member 4, rotor iron with repeated hole 122
The center of core 1 has the centre bore 13 for being used for installing rotating shaft 2, equally spacedly circumferentially there is assemble around centre bore 13 more
Repeated hole component 4.Thus, counterweight aperture member 4 is circumferentially uniformly distributed on rotor core 1.
Further, first with repeated hole 121 and second match somebody with somebody repeated hole 122 in each along rotor core 1 it is axially extending simultaneously
Form through-hole form.Thus, make weight, the shape all same of each core stamping 14, be easy to stacking accumulation installation, while counterweight
Hole is axially through form, therefore can increase relatively bigger counterweight.
As shown in Fig. 2 rotor core 1 is laminated by multiple core stampings 14, formed with each core stamping 14
One counterweight sub-aperture 141 and the second counterweight sub-aperture 142.First counterweight sub-aperture 141 forms first and matches somebody with somebody repeated hole 121 by being laminated, and second
Counterweight sub-aperture 142 matches somebody with somebody repeated hole 122 by being laminated formation second.
Specifically, the first counterweight sub-aperture 141 and the second counterweight sub-aperture 142 are by being stamped and formed out.Thus, processing is simple, just
In operation, and the one-shot forming in 14 punch forming of core stamping.
In addition, according to the component of rotor 100 of the utility model another aspect embodiment, including retouched in above-described embodiment
The rotor 100 stated.And it is arranged on described first with the first counterweight pin in repeated hole 121, is arranged on second counterweight
The second counterweight pin in hole 122.Rotor core 1 is adjusted by adjusting the quantitative proportion of the first counterweight pin and the second counterweight pin
Quality, make its uniform quality.For the component of rotor 100 other constructions such as electric control element for prior art and
It is well known to those skilled in the art, therefore is not elaborated for other constructions of the component of rotor 100 here.
In addition, according to the motor of the utility model another further aspect embodiment, including the motor turn described in above-described embodiment
Sub-component.For motor other constructions such as commutator for prior art and be that those skilled in the art is ripe
Know, therefore do not elaborated for other constructions of motor here.
