Abstract

An electric generator 1 according to the present invention comprises a controller 10, rotors 11, 12, stators 31, 32 and an electrically-driven motor 30. Two rows of magnets 15 and 16 aligned axially side by side are mounted on the rotor surface such that respective magnetic poles of respective magnets are inversely oriented alternately along the circumferential direction and the magnetic poles are different from each other in a pair of two axially aligned magnets. Each of the stators 31, 32 comprises a plurality of stator blocks, wherein a core of each block has two core end portions which can be placed in opposite to a pair of magnets of the rotor and a core intermediate portion and wherein each of the core end portions is equipped with coil 55, 56, 57, 58 wound around the core end portion. The stator block includes a stator block for electric generation, which is connected to a capacitor 50 via a bridge diode 36 and an electric generation pulse circuit 46 and a stator block for motor action, which is connected to a motor pulse circuit 48 via a bridge diode 40. The motor pulse circuit 48 comprises an electric short-circuit switch. According to the present invention, the incremental efficiency of the electric generator can be remarkably improved.

Description

technical field [0001] The invention relates to a generator, a method of generating electricity and an electric motor. Background technique [0002] In the current power generation system, the rotor of the generator is rotated using external energy (hydraulic power, thermal power, atomic power, wind power, etc.), and the method of converting the mechanical rotational energy into electrical energy is dominant. Existing generators generally include: a rotor equipped with a plurality of permanent magnets, a stator arranged around the rotor and composed of a plurality of coils, a sensor for detecting the rotation angle of the rotor, and an It is a switching circuit that switches the wiring mode of the stator coil winding so that the stator coil generates an induced electromotive force. In the existing generator, multiple coils of the stator are connected to each other, and the electricity and magnetism are not independent. [0003] The power generation principle of this mainst...
