Description
Technical field
The present invention relates to electronics rotor technical field, is specially a kind of rotor punching.
Background technology
Rotor is the rotary part in motor.Motor is made of rotor and stator two parts, it is for realizing electricity
Can be with mechanical energy and mechanical energy and the conversion equipment of electric energy.Rotor is formed by stacking by multi-disc rotor punching, at present rotor thermal diffusivity
Difference, have impact on rotor efficiency.
The content of the invention
To solve the above-mentioned problems, the present invention provides a kind of rotor punching, it can improve rotor thermal diffusivity, improve electricity
Machine rotor efficiency.
Its technical solution is such：A kind of rotor punching, it includes punching body, axis is provided among the punching body
Bearing bore, is provided with keyway on the bearing hole, the punching body edges are provided with a circle conducting bar groove, it is characterised in that in the axis
Bearing bore periphery, is provided with three circular arc being evenly arranged heat emission holes on the punching body, the radian of the circular arc heat emission hole is
60-75°。
It is further characterized by, and the keyway includes two, and one is flat key groove, another is oblique key slot；
The conducting bar groove is disposed with 58-62, and described one side wall of conducting bar groove is the center of circle of plane and the corresponding punching body,
Described another side wall of conducting bar groove is step surface；
The step surface is two-stage, and first order step surface is parallel with the base of the conducting bar groove, and second level step surface is led with described
Angle is 30 ° between the base of bar groove.
After rotor punching using the present invention, due to having opened three circular arc heat emission holes, cooling effect can be effectively played,
Improve electronic efficiency.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is conducting bar groove enlarged structure schematic diagram.
Embodiment
As shown in Figure 1, a kind of rotor punching, it includes punching body 1, bearing hole 2, bearing is provided among punching body 1
Two keyways are provided with hole 2, one is flat key groove 3-1, another is oblique key slot 3-2, and 1 edge of punching body is provided with a circle conducting bar
Groove 4, in 2 periphery of bearing hole, is provided with three circular arc being evenly arranged heat emission holes 5, the radian of circular arc heat emission hole 5 on punching body 1
Angle is 60-75 °.Conducting bar groove 4 is disposed with 40-62, selects specific number according to size model number, 4 one side walls of conducting bar groove are flat
Face and the center of circle of corresponding punching body 1, another side wall of conducting bar groove 4 are two-stage step face, first order step surface 5-1 and conducting bar groove
4 base 5-2 is parallel, and angle is 30 ° between second level step surface 5-3 and the base 5-2 of conducting bar groove, and the structure of conducting bar groove 4 can
Effectively to reduce electric and magnetic oscillation and noise, electric efficiency is further improved.
