Description

A kind of motor rotor construction
Technical field
The present invention relates to motor device technical fields, are specially a kind of motor rotor construction.
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 motor rotor construction, rotor thermal diffusivity can be improved, is carried High rotor efficiency.
Its technical solution is such:A kind of motor rotor construction is set with multi-disc including shaft, in the shaft and folds The rotor punching put, the every rotor punching edge are uniformly provided with a circle conducting bar slot, which is characterized in that the stacked rotor Punching both ends are respectively arranged with aluminium ring, are equipped with multiple blades in an aluminium ring, on the every rotor punching it is upper It is even to be installed with three circular arc heat emission holes.
It is further characterized by, and wind shield is equipped in the shaft at the blade;
The conducting bar slot is disposed with 58-62, and described one side wall of conducting bar slot is the center of circle of plane and the corresponding rotor punching, Described another side wall of conducting bar slot is step surface;
The step surface is two-stage, and first order step surface is parallel with the base of the conducting bar slot, 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, and it can be driven during rotor rotation Blade rotates, and so as to effectively play cooling effect, improves electronic efficiency.
Description of the drawings
Fig. 1 is schematic structural view of the invention;
Fig. 2 is rotor punching structure schematic diagram;
Fig. 3 is conducting bar slot enlarged structure schematic diagram.
Specific embodiment
See Fig. 1, Fig. 2, shown in Fig. 3, a kind of motor rotor construction is set with multi-disc including shaft 1, in shaft 1 and is stacked Rotor punching 2, every 2 edge of rotor punching is uniformly provided with a circle conducting bar slot 3, and stacked 2 both ends of rotor punching are set respectively There is aluminium ring 4, multiple blades 5 are installed in an aluminium ring 4, upper on every rotor punching 2 is uniformly installed with three circular arcs and dissipates Hot hole 6.Wind shield 7 is installed in shaft 1 at blade 5;Conducting bar slot 3 is disposed with 58-62, and 3 one side walls of conducting bar slot are flat Face and the center of circle of respective rotor punching 2, another side wall of conducting bar slot 3 are two-stage step face, first order step surface 3-1 and conducting bar slot 3 base 3-2 is parallel, and angle is 30 ° between second level step surface 3-3 and the base 3-2 of conducting bar slot 3, and the structure of conducting bar slot 3 can Effectively to reduce electric and magnetic oscillation and noise, electric efficiency is further improved.
