Secondth, when being passed through forward current in Exciting Windings for Transverse Differential Protection 10, outer layer iron core (as shown in Figure 3) and internal layer iron core are (such as Shown in accompanying drawing 6) each the magnetic polarity of the magnetic pole end face at open loop also occur upset to change, upper magnetic pole end face forms n pole, lower magnetic pole End face forms s pole, only forms the excitation magnetic line of force 13 producing because of magnet exciting coil excitation in outer layer iron core, and in internal layer iron core both Form the excitation magnetic line of force 18, also form the permanent-magnet magnetic line of force 19, so, define excitation in internal layer iron core upper and lower magnetic pole end With permanent magnetic overlapped compound magnetic potential, and between outer layer iron core upper and lower magnetic pole end face formed magnetic potential be only excitation magnetic potential.

3rd, when in Exciting Windings for Transverse Differential Protection, no current is passed through, as shown in Figure 4, outer layer iron core embed permanent magnet round Space forms the magnetic loop 15 of closure, and as shown in Figure 7, the permanent magnet that internal layer iron core embeds forms the magnetic of closure round space Loop 20, so, the magnetic pole end face of outer layer iron core and internal layer iron core all no magnetic potentials.

4th, when being passed through forward and reverse alternating excitation electric current to Exciting Windings for Transverse Differential Protection, will produce in the magnetic pole end face of double-deck iron core Life exchanges compound rectifier excitation magnetic field with the n.s alternating polarities of exciting current change frequency synchronised.

The present embodiment can produce composite alternating magnetic field, and the change of composite alternating magnetic field is with magnet exciting coil exciting current direction Change and change, this characteristic, open new way for it in the application of electric rotating machine, linear electric motors and transformer, can The efficiency of General Promotion electric rotating machine, linear electric motors and transformer and handling.

Embodiment two

The present embodiment is application in switching magnetic-resistance electric rotating machine for the alternation compound rectifier excitation assembly.The present embodiment electric machine structure is for example attached Shown in Fig. 8.

Ten c shape alternation compound rectifier excitation assemblies are annular in shape, equalize, be symmetrically disposed on stator seat, and each alternation is combined Excitation component is in Magnetic isolation each other, circular support 21, rotating shaft 22, and 16 permanent magnets 23 collectively form rotor.

The structure of ten c shape alternation compound rectifier excitation assemblies as shown in accompanying drawing 1 is to accompanying drawing 7, c shape alternation compound rectifier excitation assembly Iron core is double-deck c shape, is provided with c shape Magnetic isolation layer, every layer of c shape iron core is provided with two at open loop between two-layer c shape iron core Individual rectangular indentation, is inlaid with two permanent magnets respectively, is inlayed in same layer two rectangular indentation of c shape iron core in two rectangular indentation The magnetic polarity of two embedding permanent magnets is in the same direction, two permanent magnets inlayed in different layers two rectangular indentation of c shape iron core Magnetic polarity is then contrary, and its operation principle is referring to embodiment one.

16 permanent magnets 23 are embedded in circular support 21, there is gap, the magnetic of permanent magnet between two adjacent permanent magnets Polarity points to the radial direction of motor, and the magnetic polarity of two adjacent permanent magnets is different.

Rotor rotates, and on circular support, two permanent-magnet magnetic pole-faces of each permanent magnet all alternations can be combined from stator seat Skim between two magnetic pole end faces of excitation component c shape iron core, and permanent magnet unit permanent magnetism magnetic pole end face is extreme with c shape iron core magnetic Air gap is there is between face.

Because alternation compound rectifier excitation assembly is Magnetic isolation each other on stator, thus can independently carry out the sense of current and big Little control, this partial function to be realized by excitation power supply control circuit.

The control principle of the present embodiment motor is according to each c shape alternation compound rectifier excitation assembly magnetic pole end face and permanent magnet The relative position of magnetic pole, carrys out control input to the exciting current direction of c shape alternation compound rectifier excitation assembly by excitation control electric current, Reach the purpose obtaining positive-torque, avoiding negative torque, concrete control process is as follows:
