For synchronous magnetic resistance motor in normal operation, resultant magnetic field needs advanced one angle of D axles.Due to D axles and the magnetic of Q axles
Resistance so that the magnetic line of force distorts, by producing magnetoresistance come output torque.The magnetic field of equivalent, it is in the case of optimal
All by D axles, and the flux component that Q axles pass through is 0, and now torque output is maximum, and the magnetic line of force all effectively utilizes.And magnetic conduction
The relative magnetic permeability value of material is typically nonlinear, and ratio is little, therefore the presence of leakage field is inevitable.But can
Leakage reactance is reduced with accounting increase by low magnetic conduction substances such as the air on D axle magnetic circuits.Fig. 2 is that 4 pole motor symmetric rotors are led
The diagram changed over time behind magnetic arm forward position and magnetic conduction arm along the close average value of magnetic.As shown in Fig. 2 before meeting the basis of D spindle guide magnetic
Putting, for the magnetic circuit due to advanced D axles, magnetic resistance is different, and caused magnetic circuit is asymmetric on D axles, in magnetic conduction passage, from
Seen on average magnetic is close, the forward position magnetic of magnetic conduction arm is close rear close along magnetic less than magnetic conduction arm.Dotted line show the forward position of magnetic conduction arm in Fig. 2
(referred to as leading magnetic arm) magnetic is close；Rear edge (magnetic conduction arm after abbreviation) magnetic shown in solid for magnetic conduction arm is close.
Thus, on the basis of original symmetric design (i.e. the symmetrical structure of prior art), after holding along size Wrb substantially not
Become, it is appropriate to reduce front size Wrf, and asked for the average magnetic on two magnetic conduction arms is close so that the two value is suitable.According to
Above-mentioned principle designs asymmetric magnetic conduction arm configuration, the characteristics of to adapt to reluctance motor.

O'clock as two measurement points.Its subtended angle is measured with the center of circle.As shown in figure 1, relative to the symmetrical structure of prior art, only change
The width of front and rear magnetic conduction arm, its magnetic conduction arm are constant relative to the subtended angle of original symmetric design.In Fig. 1, α is magnetic conduction passage
Polar arc angle, the leading magnetic arms of β are with Q shaft angle degree, i.e.,：The β of α=2.
Structure design more than, from the angle of D axles, D axles magnetic flux is basically unchanged because former saturation position magnetic is close,
Therefore D direction of principal axis magnetic fluxs were both basically unchanged；From Q direction of principal axis, because magnetic conduction arm forward position narrows, therefore its magnetic flux barrier broadens.Deng
Imitate increases for the magnetic resistance on Q axles path, therefore leakage field reduces.Dissymmetrical structure design more than improves synchronous reluctance electricity
The salient pole ratio of machine.

In abscissa be ratio after width ratio, that is, magnetic conduction arm along width and magnetic conduction arm front porch width, i.e. Wrb/Wrf's
Value.Wrf cannot value it is too small, otherwise can form magnetic circuit saturation, play reverse effect on the contrary, be uniformly with magnetic circuit saturation
It is accurate.As shown in figure 4, changing from small to big with Wrb/Wrf, originally its corresponding salient pole ratio is increased, and is taken in Wrb/Wrf
Be worth and nearby obtain preferable effect for 1.1 (salient pole is than maximum)；Again as the value continues to increase, magnetic conduction arm forward position is due to being thinned
Excessively, saturation is serious, turns into new magnetic flux bottleneck position, serious influence D axle magnetic fluxs so that the reduction of Q axle inductances is not enough to
The decline of D axle inductances is made up, shows situation of the salient pole than decline, and the speed of downward trend is increased.Consider
Various situations, usual value are 1.05≤Wrb/Wrf≤1.15.
Fig. 5 is that the region of the direction of rotation forward position side of the asymmetric rotor structure of motor provided by the utility model is set
