Description
Technical field
The present invention relates to a kind of switched reluctance machines, particularly a kind of transverse magnetic field outer rotor switched reluctance motor.
Background technology
Switched reluctance machines are a kind of new bunchers, and its governing system has direct current concurrently, exchanges two class governing systems
Advantage, it is the latest generation stepless time adjustment system after frequency conversion speed-adjusting system, Speed Regulating System of Brushless DC Motor.Its structure letter
Single firm, speed-regulating range width, speed adjusting performance is excellent, and all has greater efficiency in whole speed adjustable range, system reliability compared with
It is high.But switched reluctance machines are mainly there is also some shortcomings：Larger, circuit control part structure is shaken under working condition
Complicated, manufacturing cost height, operation torque are up for further improving.
（1）Shaken under working condition larger
Torque ripple is the inherent characteristic of general motor, but the torque ripple of switched reluctance machines is especially big, this big ups and downs
The vibrations for causing motor under working condition are larger.
（2）Total output torque is smaller
Existing switched reluctance machines, stator and rotor use even number pole to arrange, stator two pole typically more than rotor, such as often
The internal rotor sextupole seen, external stator ends of the earth structure, there are three groups of coil windings on stator, but each moment only has one group of coil and existed
Work, that is to say, that six magnetic poles of stator, each moment only have one group（Two）Magnetic pole in action, therefore the moment of torsion always exported compared with
It is small.
（3）Controller is complicated
Because switched reluctance machines are relative come control circuit formation rotating excitation field, its controller by detecting the different azimuth of rotor
Complexity, and cost is higher.
In summary, switched reluctance machines in spite of a lot of other motors it is incomparable the advantages of, but also have itself a lot
Intrinsic determination and deficiency.
The A of application publication number CN 104362821 application for a patent for invention discloses a kind of multistage outer rotor switch magnetic-resistance electricity
Machine, the motor have still suffered from the shortcomings that total output torque is smaller, controller is complicated, cost is high.
The content of the invention
The technical problem to be solved in the present invention is：A kind of transverse magnetic field outer rotor switched reluctance motor is provided, it is existing to solve
There is the weak point that the existing output total torque of switched reluctance machines is small, controller architecture is complicated, cost is high.
Solve above-mentioned technical problem technical scheme be：A kind of transverse magnetic field outer rotor switched reluctance motor, including stator,

Son has two sets, and the rotor often covered has n to turn pole, and the stator often covered has 2n magnetic pole；Two sets of stators, which are separately mounted to stator, to be determined
It is provided with the stator sleeve of position frame both sides, and often between the two neighboring magnetic pole of set stator wherein for controlling stator coil
The photoelectricity phase changer of winding current；Two sets of rotors are arranged on the outside of two sets of stators by bearing respectively, and two sets of rotors are in axle
Be staggered α angles in line vertical plane, α=360 °/4n；Described rotor sleeve closely surround two sets of rotors it is cylindrical on, and rotor set
The internal diameter of cylinder is more than the external diameter of stator.
The present invention further technical scheme be：Described n span is：n≥2.
The present invention further technical scheme be：Coil windings on stator include coil windings A and coil windings B, line
Circle winding A and coil windings B is arranged alternately.
The present invention further technical scheme be：Described photoelectricity phase changer includes one and is used to control often set stator institute
There are the photoelectricity phase changer A of coil windings A electric currents and a photoelectricity commutation for being used to control often set stator all coils winding B electric currents
Device B, photoelectricity phase changer A are arranged between adjacent coil windings A and coil windings B, and photoelectricity phase changer B is arranged on the coil
Between winding A and the next group of coil windings B adjacent with coil windings A.
The present invention further technical scheme be：Described rotor includes n group silicon steel sheet combination blocks.
The present invention further technical scheme be：It is connected on the output circuit of described photoelectricity phase changer as it
Resistance, the two-stage switch triode of control coil winding current break-make of proper operation voltage are provided.
Due to compared with prior art, being had using said structure, the transverse magnetic field outer rotor switched reluctance motor of the present invention
There is following beneficial effect：
1. it is big to export total torque
Any instantaneous moment at most only has one group of magnetic pole of the stator and a corresponding group rotor to Conventional switched reluctance motor at work
Salient pole produces driving torque attracting each other, and any at work instantaneous moment of the present invention will have n groups magnetic pole of the stator and right
The n group rotors salient pole answered is produced and attracted each other, so as to the switching magnetic-resistance electricity of the present invention in the case of operating current identical
Machine will produce bigger moment of torsion, and the overall width of n group magnetic pole of the stator is close to the half of total circumference, and therefore, output of the invention is always turned round
Square is larger.
2. operation vibration is small：
Because the often set stator of the present invention uses two groups of coil alternations, the magnetic pole of alternation in a circumferential direction is in uniform
It is symmetrical.For Conventional switched reluctance motor, the present invention each moment in running order magnetic pole stress can be more
Add it is uniform with it is symmetrical." inertia dead band " area between coil switching is also very narrow, as number of magnetic poles n increase is this each
" inertia dead band " area will be further compromised.Therefore pulsation and vibrations will greatly reduce caused by present invention work.
3. controller architecture is simple, manufacturing cost is low
Traditional switched reluctance motor controller part is mainly position to rely on detecting system to detect the position of rotor, and according to
Positional information produces a rotating excitation field on stator.And controller circuitry part of the present invention, it is only necessary to examined in position
Survey under the instruction of signal and produce the magnetic field of two alternations.Therefore only need to use switch triode and infrared electro sensing
Switch can be achieved.The structure of controller part is greatly simplified, therefore its manufacturing cost is also very low.
In summary, the present invention uses rotor misphase combinatorial principle and infrared electro commutation circuit, both overcomes
The shortcomings that Conventional switched reluctance motor operation vibration is big, motor torque under identical operating current is set to be greatly improved again, together
When also greatly simplifie controller architecture, in the case where making the manufacturing cost of controller in the case of improving controller reliability significantly
Drop.
