Close effect.
Shown in embodiment such as Fig. 4 (a), now both sides stator A phases are powered, and specially side A is initially powered up, two sides
A has been powered, and rotor clockwise is rotated due to producing tangential magnetic pull between air-gap flux distortion rotor；When two side rotors are suitable
Hour hands are when rotating to the convex level aligned position of rotor as shown in Fig. 4 (b), and now two side A phases power off side A phases and remained powered on, and two
Side B phases are initially powered up；Rotor is rotated further when side rotor and stator aligned position as shown in Fig. 4 (c), now side A phases
Winding is powered off, and two side B phases are remained powered on, and side B phases are initially powered up, and completes a commutation, and motor is realized clockwise by that analogy

State and be powered simultaneously with phase or out-phase winding, such both sides torque can realize that superposition increase motor is exerted oneself；In addition this implementation
In mode, in the absence of process under energization phase inductance, because energized phase winding inductance size is changed as rotor-position changes,
As shown in fig. 6, inductance is maximum during rotor alignment, non-aligned position is minimum.Due to the electric torque formula of switched reluctance machines：
I is stator winding current, and L is stator winding inductance, and θ is rotor axis angle.In above-mentioned control process whenever
During certain side rotor alignment, the side stator winding power-off is controlled, so avoiding the shadow fluctuated when inductance declines to motor torque

Produce magnetic torque and come off；Wherein, the magnetic barrier type stator as shown in Fig. 7 (b), is fixed in the magnet isolation tank of casing, solves energization
The magnetic flux that phase Exciting Windings for Transverse Differential Protection is produced is leaked to no power phase stator, reduces loss.
The middle part of casing 2 is provided with the device for fixed axially sleeved composite permanent magnet 3 and magnetic conduction bar 14, makes
Axially sleeved composite permanent magnet and magnetic conduction bar are fixed in the middle part of casing, shown in such as Fig. 8 (a) -8 (b), the quantity of magnetic conduction bar 14

As shown in figure 9, casing 2 is provided at both ends with end cap 6.
The intermediate vertical face structure on two sides of rotating shaft 1 is arranged in parallel in addition to rotor, and the full symmetric centre in rotating shaft
Vertical plane.
The principle for lifting torque is as follows：The electromagnetic torque of switched reluctance machines can be common according to magnetic from energy converting between mechanical angle
It can calculate and obtain：
Wherein, W is the magnetic coenergy of motor, as shown in Figure 10, wherein, the face that curve OCB (or OA) is surrounded with i reference axis
Product represents magnetic coenergy, and it is the function of electric current and magnetic linkage, and θ is angular displacement of the rotor relative to stator.Therefore, the torque energy of motor
Power can be reflected that as shown in Figure 10, figure cathetus OA represents rotor tooth center line and stator groove center line by I- φ characteristic curves
Characteristic during position (i.e. stator and rotor tooth axis does not line up position) is overlapped, corresponding to maximum reluctance position, now due to stator and rotor
Interpolar gas is larger, and magnetic circuit is unsaturated, so being OA straight lines；And curve OCB is when representing stator and rotor pole center line aligned position
Characteristic, corresponding to magnetic resistance minimum position.
The average torque that rotor often takes a step forward is directly proportional to region OABCO encirclement magnetic coenergy increment Delta W, therefore multiphase
The average output torque of switched reluctance machines is：
Wherein, Nr be rotor number of poles, m be number of phases obviously, under same magnetic field energy, increase motor the number of phases with
And rotor number of poles can also effectively improve the output torque of motor.But for traditional structure switched reluctance machines, when outside motor
After footpath size is determined, there is mutual restricting relation between three, it is difficult to be obtained from structure.The present invention is equivalent using special construction
12/8 level structure adds rotor number of poles, lifts torque.
Because the leakage magnetic flux of regular tap reluctance motor adjacent teeth pole will produce braking moment to rotor, this will greatly
Shadow motor is exerted oneself.Therefore the present invention is using permanent magnet auxiliary.By the flow direction of axial permanent magnetic body auxiliary permanent magnet with determining
Leakage field in son, rotor core makes interelectrode magnetic leakage is logical to be obviously reduced in the opposite direction, reduces leakage field and produces braking moment.
From formula (3) it can also be seen that the torque magnification of switched reluctance machines can be realized by increasing magnetic coenergy increment Delta W,
Air-gap flux and OA in current relationship such as Figure 10 when stator and rotor tooth does not line up position；Air-gap flux during stator and rotor tooth aligned position
With OAB in current relationship such as Figure 10；The flow direction of permanent magnet is identical with the flow direction that stator winding is produced in air gap, gas
Gap magnetic flux is strengthened, therefore strengthens region OABCO encirclement magnetic coenergy incremental area Δ W.
Therefore, rotor alternate angle stator magnetic barrier type axial permanent magnetic auxiliary double salient-pole electric machine of the invention, using increasing stage
Number and lifting magnetic coenergy increment Delta W, realize lifting torque.
