A kind of composition frame chart of governing system of switched reluctance machines is as shown in figure 1, the governing system generally comprises switch Reluctance motor 100, power inverter 200, controller 300 and position sensor 400.With regard to each component units of governing system it Between control process, in the range of the understanding of those skilled in the art, no longer describe in detail herein.
This utility model embodiment provides a kind of switched reluctance machines, and the switched reluctance machines are threephase switch magnetic resistance electricity Machine, including housing and field spider and salient pole stator in housing, are wound with ABC three-phase windings on the tooth of stator.
Preferably, each phase in ABC three-phase windings includes at least three exits, draws including two ends End, positioned at winding two ends, also including at least one middle part exit, the middle part exit is located at a certain position in the middle of winding, So, when a certain exit in middle part and one of end exit are accessed into circuit, then each phase winding only has part logical Electricity work, and when two end exits are accessed into circuit, then each phase winding whole energization work, so as to realize to the shape that works The regulation of state.
For example, each phase in ABC three-phase windings is the three-phase windings with midpoint, middle part exit i.e. with winding Midpoint is connected, then winding can all access circuit and be operated, corresponding to the normal operating conditions of motor, it is also possible to it Half accesses circuit and is operated, corresponding to motor assist working condition.ABC three-phase windings can be arranged to include multiple middle parts Exit, the working condition of such motor can then have various gears to adjust.
Preferably, the present embodiment breaker in middle reluctance motor can be the default sub-motor of outer rotor, wherein, as shown in Fig. 2 fixed Attached bag is included around circumferentially spaced multiple stator tooths and the stator slot between stator tooth；Rotor is included around circumferentially disposed Multiple rotor tooths and the rotor slot between rotor tooth.The rotor 410 can be 24 grooves for the outer rotor of 16 poles, stator 420 Inner stator.
As shown in Fig. 2 the default sub-motor of the groove of 16 pole external-rotor 24 can adopt ABCABC ... order coiling, totally 24 around Set of pieces, three-phase windings respectively have the elements of winding of 8 series connection, and the element of winding using many insulated copper wires and around will thoroughly do away with edge more Copper cash is split into two halves, it is such 8 series connection the elements of winding, again formed and around two parts, have two line head ends and two lines Tail end, using one pair of which line head end and line tail end as the end exit for the phase winding, then by another to line head end and line Tail end and after connecing, as the midpoint exit of the phase winding, therefore ABC three-phase windings be the three-phase with midpoint exit around Group.Certainly, in other embodiments, each item in three-phase windings is also provided with multiple middle part exits, and extraction location It is also not necessarily limited at the midpoint of winding, in the range of the understanding of those skilled in the art, here is omitted.
Fig. 3 is referred to, Fig. 3 is the partial structurtes enlarged drawing of Fig. 2 breaker in middle reluctance motors.Preferably, it is fixed in the present embodiment The ratio of the slot bottom width L10 of the son and width L8 of stator tooth is 1～1.25, and groove depth D1 is 2～4 times of facewidth L8.This design can High with the stock utilization for ensureing motor, vibrations and noise are little.This is, because switched reluctance machines do not use permanent magnet, only to make With iron core and copper cash, when its copper consumption is suitable with iron, the stock utilization highest of motor.And switched reluctance machines are determined When the width ratio of slot bottom width and the stator tooth of son is 1, it is believed that its copper consumption is suitable with iron, slot bottom width and stator The width ratio of tooth is more than 1, then can put more copper cash.But if slot bottom width is excessive with the width ratio of stator tooth, when groove depth is When 2～4 times of the facewidth, it is meant that the width of stator tooth is too narrow, after winding is powered on tooth, stator and rotor are in strong magnetic pull Under effect, vibrations and noise are easily produced.The span of the width ratio of the groove depth, tooth and groove of this utility model stator, effectively Guarantee that the stock utilization of motor is high, namely improve the power density of motor, and inhibit vibrations and noise.
