Abstract
The utility model relates to a switch reluctance motor rotor structure, reducing air resistance of the motor rotor in high-speed running of the motor, effectively improving working efficiency of the motor, lowering noise and reducing heating of the motor rotor due to friction. The switch reluctance motor rotor structure provided by the utility model is filled with gel material at the yoke part formed between rotor teeth, and the gel material is made of insulation and nonmagnetic material without impact on magnetic circuit. The thermal expansion coefficient of the insulation and nonmagnetic gel is similar to the thermal expansion coefficient of rotor material of silicon steel, thereby avoiding crack due to great difference of thermal expansion coefficient between the insulation and nonmagnetic gel and the rotor. The switch reluctance motor rotor structure provided by the utility model is fit for motor running in high speed. The motor has low noise and less heat in running and the working efficiency is greatly improved compared with the existing switch reluctance motor.
Description
Technical field
The utility model relates to a kind of motor rotor construction, refers in particular to a kind of switch reluctance machine rotor structure that can reduce air drag that rotor is subjected to when the motor high-speed cruising, reduce noise.
Background technology
There is the tooth level in the rotor of switched reluctance machines commonly used, and the defective of bringing thus is to increase greatly along with air drag that increasing of rotating speed causes rotor to be subjected to, and the motor feels hot thereby make, and reduced the operating efficiency of motor, and can produce very big noise.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of switch reluctance machine rotor structure is provided, to reduce the windage that switch reluctance machine rotor tooth level produces, reduces noise, improve the operating efficiency of motor.
The utility model for the technical scheme that the technical solution problem adopts is: a kind of switch reluctance machine rotor structure, comprise axle 1, rotor tooth 2, yoke portion 3, bolt and nut 4, also comprise the exhausted magnetic colloid 5 of insulation, copper ring 6 and steel loop 7, the exhausted magnetic colloid 5 of insulation is filled in yoke portion 3 places that form between the rotor tooth 2, two copper rings 6 that are used for fixing the exhausted magnetic colloid 5 of insulation axially are connected in the rotor two ends by bolt and nut 4 along rotor, bolt in bolt and the nut 4 is embedded in the exhausted magnetic colloid 5 of insulation, two steel loops 7 are connected to the outside of two copper rings 6, be used to strengthen the intensity of copper ring 6, copper ring 6 and steel loop 7 are set on the axle 1.
Compare with existing switch reluctance machine rotor structure, the utility model has the advantages that:
1. the exhausted magnetic colloid 5 of insulation has been filled at yoke portion 3 places that form between rotor tooth 2, and there is the tooth level in the rotor structure that has overcome existing switched reluctance machines and the defective that causes, has reduced the air drag that rotor was subjected to when switched reluctance machines rotated greatly.
2. the air drag that motor rotor construction of the present utility model is subjected to reduces, and therefore the noise that produces is just very little, has environmental-protection function.
3. improved the operating efficiency of motor.Adopt the motor of rotor structure described in the utility model to overcome the rotating speed big more problem of air drag that is subjected to of high rotor more, improved motor working efficiency greatly.
The air drag that is subjected to of rotor more friction to give birth to heat few more, thereby reduced that the motor feels hot, the ill-effect to motor itself of avoiding generating heat helps to prolong life-span of switched reluctance machines.

Embodiment
Be described further below in conjunction with accompanying drawing:
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of switch reluctance machine rotor structure, comprise axle 1, rotor tooth 2, yoke portion 3, bolt and nut 4, also comprise the exhausted magnetic colloid 5 of insulation, copper ring 6 and steel loop 7, the exhausted magnetic colloid 5 of insulation is filled in yoke portion 3 places that form between the rotor tooth 2, two copper rings 6 that are used for fixing the exhausted magnetic colloid 5 of insulation axially are connected in the rotor two ends by bolt and nut 4 along rotor, bolt in bolt and the nut 4 is embedded in the exhausted magnetic colloid 5 of insulation, two steel loops 7 are connected to the outside of two copper rings 6, be used to strengthen the intensity of copper ring 6, copper ring 6 and steel loop 7 are set on the axle 1.
After the exhausted magnetic colloid 5 of insulation is filled at yoke portion 3 places between the rotor tooth 2, overcome that there is the tooth level in existing switch reluctance machine rotor structure and the defective that causes, the air drag that rotor is subjected to does not increase greatly with the increase of motor speed, operating efficiency when having improved the motor operation, the noise that has been produced when having reduced the motor operation, alleviated the frictional heating amount when switch reluctance machine rotor rotates, avoid heating to the harmful effect that motor itself produces, helped to prolong the switched reluctance machines life-span.
