A dynamic balance element is fixed on the rotor pressure plate. The stator-rotor structure of the motor has simple structure and low cost, and is suitable for ultra low speed and high-speed stable rotation; each pole on the stator is a single winding, and the insulation is reliable. As a, b and c phases are powered-on independently, each phase of the winding and a magnetic circuit work independently, even if a certain phase of the winding is damaged, the power supplying of the phase is stopped, the motor can continuously rotate.
Description
Technical field
The utility model relates to a kind of switched reluctance machines stator and rotor sructure, and specifically switched reluctance machines adopts 12/8 biconvex utmost point stator and rotor sructure.
Background technology
In prior art, with the utility model comparatively approaching be the mouse-cage type threephase asynchronous, the mouse-cage type threephase asynchronous adopts the threephase stator winding usually, stator and rotor groove number is more, as 36/32 groove, 48/44 groove etc., winding rule difficulty more easily produces turn-to-turn and phase fault.In case a phase winding damages, motor can't turn round.Cast-aluminum rotor cost of manufacture height is not suitable for running up.Adopt ac variable frequency speed regulation, speed adjustable range is little, and starting difficulty during low-speed running is moved not steadily, and use is restricted.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of electric machine rotor simple in structure, is easy to make, and cost is low, and dependable performance is applicable to Ultra-Low Speed and the switched reluctance machines stator and rotor sructure that runs up.
According to the technical scheme that the utility model provides, the switched reluctance machines stator and rotor sructure comprises stator core, stator winding, rotor core; Stator core, rotor core are formed with silicon steel plate stacking respectively, and feature is: evenly be distributed with 12 magnetic poles on the stator core, be wound with stator winding on the stator core circumference, the stator winding of relative two utmost points is contacted mutually, constitutes three phase windings; Rotor core is provided with 8 salient poles; At rotor core two ends fixed rotor pressing plate.Fixing dynamic balancing element on the described rotor pressing plate.
Compared with the prior art the utility model has the following advantages:
The utility model electric machine rotor is simple in structure, and cost is low, is applicable to run up; 12/8 pole switching reluctance motor structure is simpler than traditional mouse-cage type threephase asynchronous, and rotor is easy to make; Each very independent winding on the stator, insulation is reliable.Because a, b, c three-phase are switched on separately, each phase winding and the separate work of magnetic circuit even a certain phase winding damages, only need stop to power mutually to this, and motor still can remain in operation.Native system can constitute the high system of reliability thus, goes for special occasions such as aerospace.But 30 rev/mins of runnings of motor Ultra-Low Speed, particularly suitable Ultra-Low Speed and running up.
Description of drawings
Fig. 1 is the utility model switched reluctance machines structural representation.
Fig. 2 is the utility model rotor cross sectional view.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2, comprise stator core 1, stator winding 2, rotor core 3, rotor pressing plate 4 and dynamic balancing element 5 etc.
The utility model stator core 1, rotor core 3 usefulness DW470-50 silicon steel plate stackings are formed, and stator core 1 is arranged along motor cross-sectional periphery direction, and is fixed in the motor housing, stator core 1 is provided with 12 magnetic poles, evenly distributes, and is divided into three groups, every group 4 magnetic pole is 90 degree and arranges.Be wound with stator winding 2 on stator core 1 circumference, the stator winding of relative two utmost points is contacted mutually, and it constitutes A, B, C three phase windings.Rotor core 3 is also different with common motor rotor core structure.Rotor core 3 arranges along motor cross-sectional periphery direction and is provided with 8 salient poles that angle is 45 degree therebetween.At rotor iron 3 two ends fixed rotor pressing plates 4, on rotor pressing plate 4, be fixed with dynamic balancing element 5, be provided with for regulating rotor dynamic balancing.
The utility model operation principle and the course of work:
From the electromagnetic structure of motor, each phase winding and magnetic circuit are separate, produce electromagnetic torque in each comfortable certain shaft angle scope.Must produce a circle rotary magnetic field in the general motor and be unlike under each phase winding and magnetic circuit acting in conjunction, motor could run well.See on the slave controller structure that each the self-supporting phase winding power supply of each circuitry phase generally also is separate work.Hence one can see that, when motor one phase winding or controller one circuitry phase break down, need only stop this and work mutually, and motor there is no other obstruction except that the gross output ability reduces to some extent.
The utility model feeds direct current to A1, the A2 of a phase winding end, and axis place, a-a magnetic field produces two pairs of magnetic poles in the stator core, and these two rotor with salient pole that poles attract is adjoining make rotor rotation, until rotor with salient pole center line and a-a dead in line.A cuts off the power supply mutually, feeds direct current to b phase winding again, because stator poles is apart from being 60 °, rotor polar distance is 90 °, and two pairs of magnetic poles that b phase winding produces will attract adjacent rotor with salient pole to rotate 30 °, until with the b magnetic pole coincidence of winding mutually.In like manner, b cuts off the power supply mutually, and feed direct current to c phase winding this moment again, makes the adjacent rotors salient pole rotate 30 ° again.Under the jointly controlling of switched reluctance motor controller and angular displacement sensor, make a, b, c three-phase winding feed direct current successively, the energising phase sequence is a-b-c-a, then rotor rotates counterclockwise continuously.When the energising phase sequence is a-c-b-a, rotor is clockwise rotated.Change the size of phase current, can change motor torque and rotating speed.Can change the turning to of motor, torque, rotating speed, braking by controller.
