Abstract
The utility model discloses a novel reluctance motor turning on/off apparatus comprising a stator, a stator magnetic pole, a housing, and a motor seat. A specific rubber isolating layer equipped with heat dissipating holes is arranged between the stator magnetic pole and the housing in order to form elastic connection. Therefore, the effect of pulling force generated on the stator magnetic pole on the entire housing is decreased when a rotor is rotated. The rubber isolating layer has a buffering effect so as to decrease the vibration and the noise of the entire motor. A rubber layer matched with the outline of the housing is arranged at the joint of the motor housing and the motor seat in order to decrease the vibration of the housing and the motor seat when the motor vibrates. Therefore, mutual abrasion is reduced and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of New Type of Reluctance Machines opening and closing device, switched reluctance machines is a kind of motor based on variable reluctance principle design, the power inverter of this form has been avoided two danger that switch element is straight-through, thereby improved the reliability of drive system, its application is included on Aeronautics and Astronautics as the driving of driving, electric bicycle and the motorcycle of the drive system of starting/generator, weaving, colliery, petroleum machinery, washing machine, air conditioner etc.
Background technology
On the structure principle of traditional switched reluctance machines, adopt double-salient-pole structure, rotor salient pole is overrided to form by ordinary silicon steel disc, rotor both without excitation winding also without permanent magnet.For fear of rotor unilateral magnetic force, radially must be symmetrical, so the stator of double-salient-pole and rotor teeth groove number should be even number, and rotor teeth groove number should approach as far as possible.But non-linear due to the double-salient-pole structure of switched reluctance machines and the height saturation characteristic of local magnetic circuit and switch, causes inevitable torque pulsation, causes noise to increase, and affects operating efficiency.During switched reluctance machines operation, the electromagnetic force that stator and rotor produce can be divided into tangential force and two components of radial load.Tangential force component produces the electromagnetic torque that makes electric machine rotation, although it is an electromagnetic torque for pulsation, experiment showed, that it is not main noise source, just a potential noise source.It can make rotor operation not steady, and the axle that may cause load system is resonance, need to when motor connects with load, adopt elasticity to be connected measure and be avoided.And not only radial force component can not produce the electromagnetic torque that makes motor rotation, try hard on the contrary compress air gap between rotor, make stator core produce radial deformation.The stator radial vibration that noise causes with radial load is directly relevant, because stator is shell structure, therefore inevitably can form compand vibration, by the outside shot noise of casing.
Utility model content
The purpose of this utility model is the weak point for prior art, and a kind of switched reluctance machines structure is provided, and by changing electric machine structure, reduces noise, improves the operating efficiency of motor.
The stator core of switched reluctance machines of the present utility model adopts rubber interlayer elasticity to be connected with casing, by resilient rubber interlayer, the iron core of stator being fixed to casing gets on, in the time of can accomplishing switched reluctance machines running, the vibration of casing is more much smaller than iron coring vibration, thereby reduce the noise of motor itself, and due to the reducing of casing vibration, avoid the resonance of other parts of causing due to casing tangential vibrations to produce noise., can there is serious heat dissipation problem in the double-salient-pole inherent characteristic due to switched reluctance machines, the rubber interlayer adopting between the stator core of switched reluctance machines of the present utility model and casing has louvre, heat radiation when it contributes to motor rotation when motor rotation.
Switched reluctance machines of the present utility model is also installed rubber blanket in the junction of motor and support simultaneously, avoids causing larger noise because motor oscillating causes the low-frequency resonance of support.
