Abstract
A magnetic pole structure of switched reluctance motor is provided with magnetic poles on the stator of switched reluctance motor, trenches between the two adjacent magnetic poles, circled around with inductive loop on the magnetic poles. On the rotor of switched reluctance motor is distributed with magnetic poles, and between the two adjacent magnetic poles are equipped with trenches. Magnetic poles which number is integer times of seven are uniformly distributed on the rotors. The air gap width of the magnetic poles is the same as that of trenches. Magnetic poles which number is integer times of six are uniformly distributed on the stators. Before the radial application force reaches the highest and the air gap tangential application force reaches the lowest, another group of magnetic poles have produced radial and air gap tangential application force. The compositive radial application and compositive air gap tangential application force produced by the two groups of magnetic poles can reduce the pulsation amplitude of electromagnetic torque. Thereby, the pulsation and noises of switched reluctance motor are reduced.
Description
Technical field:
The utility model relates to a kind of field structure of switched reluctance machines.
Background technology:
Switched reluctance machines is clocklike to provide power supply to coil on the multi phase stator by controller, thereby produces rotation torque, the driving rotor rotation.Because switched reluctance machines has remarkable energy saving effect and is extensively paid attention to.But there is the big and big open defect of noise of pulsation in the switched reluctance machines course of work.Make the switched reluctance machines range of application be restricted.As Chinese patent " 03109449.X " a kind of " the reduction noise structure of switched reluctance machines " number proposed just.This technical scheme is provided for changing the additional coasting body of resonance frequency by the side at rotor, reduces noise.But the use meeting loss more energy of coasting body, the volume of increase switched reluctance machines improves manufacturing cost.Therefore, this kind scheme is being used undesirable with battery-driven electric motor car.
Summary of the invention:
The purpose of this utility model is: provide that a kind of noise is little, the field structure of the switched reluctance machines of good energy-conserving effect.The utility model is achieved through the following technical solutions:
A kind of field structure of switched reluctance machines, the stator of switched reluctance machines is provided with magnetic pole, is provided with fluting between two adjacent magnetic poles, is wound with induction coil on the magnetic pole; Be distributed with magnetic pole on the rotor of switched reluctance machines, be provided with fluting between two adjacent magnetic poles.An integral multiple magnetic pole of even distribution 7 on the rotor; The width of air gap of magnetic pole is identical with the width of air gap of fluting; Stator is provided with an integral multiple magnetic pole of 6; Two adjacent field axis angulations apart near on the stator are identical with rotor two adjacent field axis angulations; Total three-phase current loop on the stator.
7 the integral multiple magnetic pole owing to evenly distribute on the described rotor; Stator is provided with an integral multiple magnetic pole of 6; It can make the magnetic pole between stator and rotor produce dislocation clocklike, and controller control stator is switched on when separating fully with epitrochanterian magnetic pole, outage when overlapping fully.
When coil electricity, according to the magnetic resistance minimum principle, the magnetic line of force is always pressed the path closure of magnetic resistance minimum, thereby produces magnetic torque.In the present invention, when stator and epitrochanterian one group of magnetic pole are finished when overlapping, another group is just being changeed magnetic pole and is being switched on and be between stator and rotor 2/5 width of air gap and overlap the place; That is to say, that radial effect power on one group of magnetic pole does not reach is maximum, the air gap tangential forces does not reach hour, another group magnetic pole has produced radial effect power and air gap tangential forces, synthetic radial effect power and synthetic air gap tangential forces that these two groups of magnetic poles produce, the pulsation amplitude of electromagnetic torque is reduced, thereby reduced the pulsation and the noise of switched reluctance machines.Because the utility model is provided with the three-phase current loop, it can make switched reluctance machines have the function of counter-rotating.
In the utility model, two near adjacent magnetic poles of distance constitute a phase current loop on the described stator.It makes the magnetic line of force of the utility model switched reluctance machines the shortest, can economize few a part of magnetic consumption, plays energy-conservation effect.
In the utility model, 14 magnetic poles evenly distribute on the described rotor; Stator is provided with 12 magnetic poles.Adopt said structure, can be made into the field structure of the switched reluctance machines of three-phase two moments of torsion.
In the utility model, 21 magnetic poles evenly distribute on the described rotor; Stator is provided with 18 magnetic poles.Adopt said structure, can be made into the field structure of the switched reluctance machines of three-phase three moments of torsion.
