Description
Technical field
The present invention relates to electronics rotor technical fields, are specially a kind of rotor punching structure.
Background technology
Rotor is the rotary part in motor.Motor is made of rotor and stator two parts, it is for realizing electricity
It 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 affects rotor efficiency.
The content of the invention
To solve the above-mentioned problems, the present invention provides a kind of rotor punching structure, rotor thermal diffusivity can be improved, is carried
High rotor efficiency.
Its technical solution is such：A kind of rotor punching structure, it is each described including the rotor punching that multi-disc is stacked
It is provided with that size is identical and the corresponding bearing hole in position among rotor punching, keyway, the rotor punching is provided on the bearing hole
Edge is provided with a circle conducting bar slot, which is characterized in that circle circle is provided on the bearing hole periphery, each rotor punching
The corresponding heat dissipation circular hole of the heart, the axial direction of size along the rotor punching of the heat dissipation circular hole is set from small to large to be formed taper and leads to
Hole.
It is further characterized by, and the keyway includes two, and one is flat key slot, another is oblique key slot；
The two side walls of the conducting bar slot are the step surface being arranged symmetrically, the symmetry axis radial arrangement of the step surface.
After adopting the structure of the invention, due to being provided with heat dissipation circular hole on each rotor punching, and the circular hole that radiates
The axial direction of size along the rotor punching is set from small to large forms conical through-hole, can effectively improve heat dissipation effect, so as to
Improve electronics rotor efficiency.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is rotor punching side view；
Fig. 3 is conducting bar slot enlarged structure schematic diagram.
Specific embodiment
See Fig. 1, Fig. 2, shown in Fig. 3, a kind of rotor punching structure, including the rotor punching 1 that multi-disc is stacked, each rotor
It is provided with that size is identical and the corresponding bearing hole 2 in position among punching 1, is opened on bearing hole 2 there are two keyway, one is flat key slot 3-
1, another is oblique key slot 3-2, and 1 edge of rotor punching is provided with a circle conducting bar slot 4, in 2 periphery of bearing hole, each rotor punching 1
On be provided with a circle center of circle it is corresponding heat dissipation circular hole 5, heat dissipation circular hole 5 size set from small to large along the axial direction of rotor punching 1
Form conical through-hole 6.The two side walls of conducting bar slot 4 are the two-stage step face 7 being arranged symmetrically, the symmetry axis radial direction cloth of step surface 7
It puts, the structure of conducting bar slot 4 can effectively reduce electric and magnetic oscillation and noise, further improve electric efficiency.
