A method of generating electricity by an alternator and a generator are disclosed. The method comprising: connecting in series stator coils of two multi-pole permanent-magnet generators that can generate equiamplitude alternating currents of different frequency, so as to make the equiamplitude alternating currents of different frequency generated by the two multi-pole permanent-magnet generators superimposed on each other to generate an amplitude-modulation alternating current with envelope lines having an amplitude changing with voltage difference of two equiamplitude alternating currents, then rectifying the amplitude-modulation alternating current positively and negatively through a controlled rectifying circuit, and filtering to form an alternating current output having frequency of the envelope lines. The alternator manufactured by this method has not only all the advantages of the existing inverting generator, but also a manufacturing cost consumedly lower than the existing inverting generator, even lower than a general universal generator, meanwhile without the high-frequency radio electromagnetic wave, thus meeting the existing European EMC certification requirements. |
