A shaft deflection type permanent magnet generator

Abstract

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.

Description

technical field [0001] The invention patent relates to the technical field of generators. Background technique [0002] The realization of multi-degree-of-freedom motion is currently considered more in electric motors, and motors with structures such as DC, stepping, synchronous, reluctance, induction, and ultrasonic have appeared successively. However, in the field of generators, the The innovative design and application of multi-degree-of-freedom-driven thinking is of great significance and value, and there is little special research and design. For multi-degree-of-freedom transmission, etc., the traditional method is to use multiple single-degree-of-freedom drive elements to cooperate with mechanical transmission devices, which will easily lead to a decrease in accuracy and efficiency, and often have a large volume and high cost. In traditional generators, the drive shaft is required to have a strict vertical relationship with the plane of the generator where the stator ...
