Title:
POWER GENERATOR HAVING REDUCED MAGNETIC FORCE RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2018/123128
Kind Code:
A1
Abstract:
Provided is a power generator that reduces magnetic force resistance and has excellent power generation efficiency. This power generator has a cylindrical rotor 3 mounted to a rotation shaft 2 rotatably supported by a housing 1, a cylindrical inner stator 4 disposed concentrically with the rotor 1 fixed to the housing 1, and a cylindrical outer stator 5 concentrically disposed on the outer side, wherein: a plurality of permanent magnets 31 are disposed in a cylindrical shape in a state where the magnetic poles are alternately different in a rotation direction of the rotor 3; in the inner stator 4 and the outer stator 5, plural coils 41, 51 for generating AC voltage when the rotor 3 is rotated are arranged side by side at positions opposing the permanent magnets 31 disposed at the rotor on a side facing the rotor; and at least one of coils 41, 51 disposed in the inner stator 4 and the outer stator 5 is set as a high inductance coil.
