The invention provides a rotation shaft deflection type permanent
magnet power generator, relating to the technical field of a power generator. A
stator is arranged at the periphery of a rotor, the rotor comprises an annular rotor magnetic yoke inner core, the annular rotor magnetic yoke inner core is made of a magnetic conduction material, a plurality of rotor permanent magnets are arranged on the periphery of the rotor magnetic yoke inner core, N poles and S poles of all rotor permanent magnets in a circumferential direction are alternatively arranged, a
magnetic isolation sheet made of a non-magnetic conduction material is arranged between each two adjacent rotor permanent magnets, a
stator groove is arranged on the inner side surface of the
stator, a distributed winding is embedded into the groove, a side, opposite to the rotor, of the stator is of a
concave surface shape, and the rotation shaft is a dual-sided or single-sided shaft and connected with the rotor magnetic yoke inner core. The rotation shaft deflection type permanent
magnet power generator still can normally generate power when the rotor deflects, namely, a certain angle is formed between the axial line of the rotor and the axial line of the stator; the rotation shaft deflection type permanent
magnet power generator has the advantages of stable power generation, simplicity in structure and relatively low cost; with the additional arrangement of a concentrated winding for deflection, a power-driven state can be entered in short time when the
deflection angle of the rotor is required to be actively adjusted; and the rotation shaft deflection type permanent magnet power generator can be widely applied to the fields of
wind driven power generation, vehicles and the like.
