external stator 1-3 is salient-pole structure,Wherein external stator core portion is made up of magnetic conductive iron,Nested outer motor permanent magnet 1-2 on each stator tooth,And stator tooth is provided with armature winding 1-4 outside in outer motor three-phase set;Magnetic conduction bridge 2-1 and magnet isolation tank 2-2 is distributed between external stator 1-3 and inner stator 3-3, lays magnet exciting coil 2-3 in magnet isolation tank 2-2;Internal rotor 3-1 is positioned at the inside of inner stator 3-3, composition inner rotor core, internal rotor 3-1 and inner stator 3-3 is salient-pole structure, wherein internal stator iron core part is made up of magnetic conductive iron, nested interior motor permanent magnet 3-2 on each stator tooth, and on inner stator tooth, it is provided with armature winding 3-4 in interior motor three-phase set.Magnet isolation tank 2-2 and magnetic conduction bridge 2-1 is distributed between inner stator 3-3 and external stator 1-3.Often set stator contains inside and outside two stators, such as stator tooth A1 and stator tooth a1.Each stator core is embedded with permanent magnet, often two pieces of permanent magnet polarities under set stator tooth are contrary, and magnet steel polar contribution under adjacent stators tooth interlocks, if i.e. permanent magnet polarity distribution N-S under first set stator tooth, then the permanent magnet polarity under that set stator tooth adjacent thereto is S-N.Magnetic conductive groove is laid magnet exciting coil, reaches the effect every magnetic and adjustable magnetic.If the inside and outside stator number of teeth is allP s , then one 2 are hadP s Block permanent magnet is nested in stator tooth, and one hasP s Individual magnet isolation tank is supplied to Exciting Windings for Transverse Differential Protection.Often in set three-phase set, each coil of armature winding is all across often on set stator tooth, and wherein, for external stator, in three-phase set, armature winding one hasP s Individual concentration armature coil is alternately distributed successively with the order of ABC three-phase, every byP s / 3 armature coil compositions, each coil space belonging to homophase differs 1080 each othero/P s (space mechanism angle).If with 12 grooves of a stator, the composite excitation compound flux switch permanent magnet motor of 10 poles of rotor is example, then first concentrate armature coil, the 4th concentration armature coil, the 7th concentration armature coil and the tenth to concentrate armature coil (space difference 90o), order series winding (or and connecting) forms A phase armature winding afterwards;Then second armature coil, the 5th concentration armature coil, the 8th concentration armature coil and the 11st is concentrated to concentrate armature coil (space difference 90o), order series winding (or and connecting) forms B phase armature winding afterwards;Then the 3rd armature coil, the 6th

As in figure 2 it is shown, when rotor is when this position, inner and outer rotors all has a tooth and stator tooth to align, and the direction of magnetization according to permanent magnet, the permanent magnet flux direction values in two armature coils is maximum.Therefore, if applying the electric excitation magnetic potential in opposite direction with permanent magnetic potential by magnetic winding coil, the electro-magnetic flux making generation is in opposite direction with permanent magnet flux, then can reduce the synthesis magnetic linkage in inside and outside armature coil simultaneously, and then reduce the electromotive force of sensing in armature winding.In Fig. 2 shown in permanent magnet flux linkage 4-1, when rotor is when position shown in Fig. 2, motor is example in addition, external stator 1-3 has a tooth relative with the rotor tooth of outer rotor 1-1, the direction of magnetization according to permanent magnet differentiates, in coil, the permanent magnet flux of linkage passes this stator tooth, penetrates rotor pole through air gap, and now permanent magnet flux numerical value is maximum.Pass into weak magnetoelectricity stream to Exciting Windings for Transverse Differential Protection, the electric excitation flux linkage contrary with permanent magnetic potential will be produced, in Fig. 2 shown in excitation flux linkage 4-2, excitation flux linkage passes rotor tooth, through air gap, penetrates stator, reduce the magnetic flux of armature coil institute linkage, thus reducing the electromotive force induced.Equally, internal structure has identical operation principle.Adopt electricity excitation and permanent magnet as the excitation source of motor, it is possible to be greatly improved motor gas-gap field controllable, thus improving motor performance and work efficiency simultaneously.
Permanent magnet 1-2,3-2 of external and internal compositions is the other types permanent magnet materials such as ferrite, SmCo or neodymium iron boron, interior external stator 1-3,3-3, inner and outer rotors 1-1,3-1 and magnetic conduction bridge can adopt silicon steel punched chip laminated to make, and the magnet isolation tank 2-2 outputed between interior external stator is for placing Exciting Windings for Transverse Differential Protection.
Additionally, the feature on this electric machine structure causes that its unloaded air gap flux density is relatively big, motor has stronger torque output capability, and power density is higher;Meanwhile, armature winding and Exciting Windings for Transverse Differential Protection are all concentratred winding, and end is short, and resistance is less, and efficiency is higher.
