According to said structure, when singly to utmost point rotor 11N and 11S rotation, by arc-shaped magnet 12,13,15 and 16 produce a rotating magnetic field that causes electromagnetic induction in stator core 7 to 10.As explaining with reference to figure 6 and Fig. 7, when the magnetic line of force number of a winding increased in passing winding 7c to 10c, the magnetic line of force number that passes an adjacent winding among the winding 7c to 10c just reduced.Therefore just, to a given winding, the magnetic line of force periodically increases and reduces, and has the square waveform similar to square waveform shown in Figure 7 from one of first series circuit (7c-10c) output, and the cycle is 1/2 first electromotive force of swing circle.
When the magnetic line of force number of a winding increased in passing winding 27c to 30c, the magnetic line of force number that passes an adjacent winding among the winding 27c to 30c just reduced.Just, to a given winding, the magnetic line of force periodically increases and reduces, and is therefore anti-phase with 180 ° of first electromotive force from one of second series circuit (27c-30c) output, and has second electromotive force of the square waveform of same period with first electromotive force.Just, 180 ° of second electromotive force and electromotive force shown in Figure 7 are anti-phase.
With reference to Figure 10, according to the detection signal of Magnetic Sensor 31 and 32 outputs, switch SW 1 and SW2 carry out switching at interval with 90 °.Therefore, with 180 ° at interval alternate selection have square waveform and the positive component I and the III of first electromotive force that provides from first series circuit, and have square waveform and the positive component II and the IV of second electromotive force that provides from second series circuit, and output to output 18 and 19.
This means that present embodiment guarantees efficient energy conversion is arranged, wherein eliminate counter magnetic field, and suitably synthetic and export a direct electromotive force. with positive level.Certainly may by switch regularly 180 ° of phase shifts with synthetic and export a negative direct electromotive force..
