The present invention relates to a generator using two rotors that can use a rotating shaft or a fixed shaft, and more particularly, to a first rotor and a magnetic body or a plurality of magnets formed of a magnetic body or a plurality of divided magnets. The present invention relates to a generator capable of generating electricity by reducing rotational resistance of a rotor and increasing power generation efficiency by simultaneously rotating the molded second rotor.

The magnitude of the electromotive force generated by the generator is proportional to the strength of the magnetic field, the length of the conductor and the relative speed of the magnetic field and the conductor.

Therefore, the electromotive force can be increased by increasing the strength of the magnetic field or forming a long conductor, or by increasing the relative speed of the magnetic field and the conductor. Typically, the relative speed of the magnetic field and the conductor is increased to increase the electromotive force. To this end, the rotational speed of the rotor needs to be increased. In this case, high-speed rotation is required. Couldn't get it.

The rotary shaft 110 is rotated by the power generated by the external power generating means, both ends thereof are rotatably supported by the rotary shaft support a, b (111, 113).

The first rotor 120 is formed of a magnetic body or a plurality of magnets 156 divided in a cylindrical shape and fixedly coupled to an outer side of the rotation shaft 110.

The stator 130 is positioned between the first rotor 120 and the second rotor 150, and forms the core 134 for winding the coil into a composite soft material or a nonmagnetic material.

The first rotor 220 has a snap ring or circlip 254 at both ends of the first rotor coupling bearing 222 coupled to the outer circumferential surface of the fixed shaft 210 to be slipped. Do not move from side to side.

The stator 230 is positioned between the first rotor 220 and the second rotor 250 and forms a core for winding the coil into a composite flexible material or a non-conductor.

In order to support the stator 230, the center portions of the stator side plates a 231 and the stator side plates b 232 are fixed to the both ends by using a coupling mechanism 235 such as a key or precision machining. It is fixedly fixed to the outer circumferential surface.

Only one of the stator side plates a 231 and the stator side plates b 232 is used to fix the wiring 242 to the side plates.

When a rotational power caused by external force is generated on the second rotor 250, the first rotor 220 coupled to the fixed shaft 210 to be slipped at the same time has the same rotation angle in the same direction. It will make constant speed rotation. That is, since the first rotor 220 and the second rotor 250 are coupled to the fixed shaft 210 and slip, the first rotor 220 is attracted by a force that tries to stick to each other by magnetic force. And the second rotor 250 makes the same rotation angle in the same direction at the same time to make a constant rotation.
