Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
A kind of Mutual Inductance Coupling type switched reluctance machines of the present invention, comprises stator 1, the concentrated winding 2 of Mutual Inductance Coupling type and rotor 3.Stator 1 is provided with even number stator tooth, between adjacent stators tooth, forms stator slot, and each stator tooth radially has another stator tooth corresponding thereto along stator.On stator tooth, be wound with and concentrate winding coil 2, it is two layer winding structure, be nested on all salient pole teeth of stator 1, in each stator slot, be placed with two circle limits that belong to different coils, all stator tooths have coil nested, the number of coil equals the number of stator tooth, and every phase winding is comprised of series connection or parallel connection or the also series-parallel connection of going here and there several coils.
Further, the all coils of described concentrated winding 2 around to identical, pass into the electric current of equidirectional even to all phase windings, the magnetic linkage polarity identical (all point to radially inner side or all point to radial outside) that they produce on stator tooth, like this, when a certain phase winding of motor is switched on, the magnetic linkage of its generation cannot be completely successfully from self phase winding circulation, can be forced to flow through from other phase winding, motor can produce obvious mutual inductance.Like this, the self-induction of motor and mutual inductance all clearly, and all can be thereupon the variations of rotor-position and change.
Further, described stator 1 and rotor 3 are salient-pole structure, and rotor 3 can be internal rotor, or external rotor.When rotor 3 is internal rotor, stator 1 is positioned at the outside of rotor 3.When rotor 3 is external rotor, stator 1 is positioned at the inner side of rotor 3.On rotor 3 without winding and permanent magnet.
The working mechanism of Mutual Inductance Coupling type switched reluctance machines of the present invention is: follow magnetic resistance minimum principle, magnetic flux is always closed along the path of magnetic resistance minimum (magnetic conductance is maximum).When stator tooth and rotor tooth center line do not overlap, when magnetic conductance is not maximum, magnetic field will produce magnetic pull, forms reluctance torque, makes rotor 3 forward the position of magnetic conductance maximum to.
As shown in Figure 1, in tradition threephase stator 12 grooves/rotor 8 pole switching reluctance electric machine structures, on stator, there are 12 concentrated winding coils, by being counterclockwise called successively first, concentrate winding coil to the 12 to concentrate winding coil, wherein: first concentrates winding coil and the 7th to concentrate winding coil radially relative, the 4th concentrates winding coil and the tenth to concentrate winding coil radially relative, above-mentioned four coils can order serial or parallel connection or string series-parallel connection after form A phase winding, and the magnetic linkage direction after four coil electricities in a phase winding is mutually suitable; The 3rd concentrates winding coil and the 9th to concentrate winding coil radially relative, the 6th concentrates winding coil and the 12 to concentrate winding coil radially relative, above-mentioned four coils can order serial or parallel connection or string series-parallel connection after form B phase winding, and the magnetic linkage direction after four coil electricities in a phase winding is mutually suitable; Second concentrates winding coil and the 8th to concentrate winding coil radially relative, the 5th concentrates winding coil and the 11 to concentrate winding coil radially relative, above-mentioned four coils can order serial or parallel connection or string series-parallel connection after form C phase winding, and the magnetic linkage direction after four coil electricities in a phase winding is mutually suitable.Like this, motor utilizes self-induction to change the reluctance torque work producing, and winding and utilance unshakable in one's determination are all lower.
The winding construction of Mutual Inductance Coupling type switched reluctance machines of the present invention is different from traditional switch reluctance motor structure.Magnetic linkage direction in traditional switch reluctance motor after several coil electricities of every phase winding is mutually suitable, and magnetic linkage can circulate smoothly in phase winding own, other phase winding of can not flowing through.Like this, the mutual inductance of motor is very little, almost can ignore, and every phase winding self-induction of motor changes and changes with rotor-position, and motor relies on because self-induction changes the reluctance torque work producing.Mutual Inductance Coupling type switched reluctance machines of the present invention by winding around to change, the magnetic linkage direction of rear each coil of every phase winding energising is offseted, after a phase winding energising, the magnetic linkage of its generation cannot circulate smoothly at phase winding own, can be forced to flow through from other phase winding, like this, the mutual inductance meeting of motor is very large.In fact, the self-induction of every phase winding of Mutual Inductance Coupling type switched reluctance machines of the present invention and mutual inductance all change and to change with rotor-position, and motor relies on because self-induction and mutual inductance change the reluctance torque work producing simultaneously, and it is exported torque formula and is:

Key of the present invention, for not change under the condition of electric machine rotor core construction and size, only, by changing winding construction, changes the operational mode of motor, can make the stock utilization of motor be improved, and can make again the torque pulsation of motor be inhibited.
The present invention can be applied to any number of phases except phase structure, the switched reluctance machines that rotor teeth groove number of poles combines arbitrarily.Take below threephase stator 12 grooves/rotor 8 pole switching reluctance motors as embodiment illustrates technical scheme of the present invention and operation principle thereof.
