[0002] Traditional generator is generally only one coil rotor, stator magnetic pole does not rotate;Or only one magnetic pole rotor, stator coil does not rotate, and rotor and stator are on the same geometric center axis;Generator in normal operation, the magnetic resistance of induced current magnetic field to rotor is great, so that generator needs great power input, can maintain normal operating state, reduces the power generation efficiency of generator. SUMMARY

[0003] The present application aims at providing a kind of multi-rotor generator, by adopting magnetic pole rotor and multiple coil rotors not in the same geometric center arrangement, magnetic pole rotor rotates around fixed shaft, coil rotor rotates around coil rotor shaft, to reduce the magnetic resistance of induced current magnetic field to magnetic pole rotor, reduce the mechanical energy consumed by generator equipment, make mechanical energy more into electric energy, improve the power generation efficiency of generator, effectively solve the above problems existing in background art.

[0004] The technical scheme of the present application is: a kind of multi-rotor generator, including fixed shaft, magnetic pole rotor cover plate, coil rotor shaft, coil rotor cover plate, current collector ring, induction coil, coil rotor, coil rotor support, coil rotor bearing, magnetic pole rotor and magnetic pole rotor bearing, the magnetic pole rotor is internally provided with permanent magnet or field winding, coil rotor is stacked by silicon steel sheet and is wound with multiple groups of induction coils on it, coil rotor one end is connected output current collector ring, when magnetic pole rotor is rotated by applying external force, the coil closest to the nearest end of magnetic pole rotor generates induced current, and the magnetic field of induced current hinders the rotation of magnetic pole rotor (i.e. the magnetic field of induced current always hinders the change of magnetic flux that causes induced current), while coil rotor is not fixed, it can rotate around coil rotor shaft, coil rotor induced current magnetic field is cyclically pushed by magnetic pole rotor magnetic field, so that coil rotor generates rotation, in turn reduces the magnetic resistance of generator.

[0005] The present application has the beneficial effects that: reduce the magnetic resistance of generator, reduce the mechanical energy consumed by generator equipment, make mechanical energy more into electric energy, improve the power generation efficiency of generator.
