It is by the A fluted discs 39 and B fluted discs 40 on rotor 1 first after electric machine controller 43 starts in work Determine left inside magnet steel ring 6, left outside magnet steel ring 27, it is right in magnet steel ring 9, on right outer steel ring 21 every block of magnet steel center line, with a left side Interior pole tooth 32, left outer pole teeth 29, right interior pole tooth 17, the position relationship of the center line of right outer pole teeth 20；Now take in the right side in pole tooth 17 Exemplified by one phase pole tooth, when motor is set to turn clockwise, right interior pole tooth 17 has three kinds of working conditions：The first work shape State, as shown in Figure 3：When the center line of the right interior pole tooth 17 of the phase and the center line of N poles magnet steel in certain block on right internal rotor 7 are wrong Open, now the magnet steel on the right internal rotor 7 corresponding to the center line of the right interior pole tooth 17 of the phase, its left side is interior S poles magnet steel, the right side When side is interior N poles magnet steel, the A fluted discs 39 on rotor 1 are not produced now to the corresponding A groups sensor 37 of pole tooth 17 in the right side Stop, and now B fluted discs 40 generate stop to B groups sensor 38, therefore B groups sensor 38 is signal output of not doing work , only A groups sensor 37 just has acting signal output, and the end of pole tooth 17 in the right side of winding 16 produces one in the right side being now powered Individual N pole fields, according to magnetic field, there is a natural attraction between the sexes, the operation principle that identical charges repel each other, now N poles magnetic produced by the right end of interior pole tooth 17 , an attracting couple can be produced with the interior S poles magnet steel on right internal rotor 7, and then can with the interior N poles magnet steel on right internal rotor 7 A couple of repelling each other is produced, now in the presence of right stator 3, attracting couple and couple of repelling each other can be while the driving rotors 1 that does work Turn clockwise.

Second of working condition, as shown in Figure 4：With the rotation of rotor 1, when the center for rotating to the right interior pole tooth 17 of the phase During the center line overlap of line and the interior S poles magnet steel on right internal rotor 7, A fluted discs 39 constitute blind area 42 with B fluted discs 40 and A groups are passed Sensor 37 and B groups sensor 38 all generate stop, signal output of not doing work, now A groups power model 47 and B group power moulds Block 48 is all without power output.

The third working condition, as shown in Figure 5：With the rotation of rotor 1, when the center line of pole tooth 17 in this mutually right side and the right side After the center line of interior S poles magnet steel on internal rotor 7 staggers again, now this it is mutually right in pole tooth 17 center line corresponding to the right side When to be the ultra-Right sides of N on the left of magnet steel on internal rotor 7 be S poles, now B fluted discs 40 do not stop B groups sensor 38, and A fluted discs 39 Stop is generated to A groups sensor 37, therefore A groups sensor 37 is signal output of not doing work, only B groups sensor 38 is There is acting signal output, because acting electric current and the A groups power model 47 and the instruction of A groups sensor 37 of instruction commander's output are commanded The acting electric current of output is opposite, and the end of pole tooth 17 in the right side of winding 16 produces a S pole field, root in the right side being now powered According to magnetic field, there is a natural attraction between the sexes, the operation principle that identical charges repel each other, now S pole fields produced by the right end of interior pole tooth 17, can be with turning in the right side Interior N poles magnet steel on son 7 produces an attracting couple, and can then produce a mutual expelling force with the interior S poles magnet steel on right internal rotor 7 Even, now in the presence of right stator 3, attracting couple and couple of repelling each other can be while the driving rotor 1 that does work turn clockwise；According to upper Described, remaining each phase by that analogy, constantly close under the control of total control module 44 by acting one -- done work again after the change of current, week And renew, driving rotor 1 rotates.
