Abstract

The invention relates to a self-stabilizing centrifugal permanent magnet generator, which comprises a stator I and an outer rotor II, wherein the stator I comprises a stator core and stator windings, wherein the stator windings are evenly distributed on the stator core in a circumferential form; the outer rotor II comprises permanent magnets, an outer rotor core, rotor slide blocks, guide locking rods, a protective sleeve, damping blocks, reset springs, pressure plates, gaskets and locking nuts; a plurality of permanent magnets and rotor slide blocks are alternately and evenly distributed in the outer rotor core in the circumferential form; a cavity is processed in each rotor slide block; each guide locking rod, each damping block, each reset spring, each pressure plate, each gasket and each locking nut are arranged in the corresponding cavity; and the guide locking rods are fixedly connected with the outer rotor core. The internal magnetic resistance of the rotor is changed by centrifugal force generated in the generator rotating process, so that the self-stabilizing target of the permanent magnet generator is achieved by changing the size of an exciting magnetic field; the structure is simple; and the cost is low.

Description

technical field

[0001] The invention relates to the field of generators, in particular to a self-stabilizing centrifugal permanent magnet generator. Background technique

[0002] Permanent magnet generators have the characteristics of small size, high power density and high efficiency. Compared with electric excitation generators, they have obvious energy-saving effects. The Chinese patent centrifugal rotor permanent magnet generator (application number: CN02135709.9) provides a high-efficiency permanent magnet generator solution, but the output voltage of the permanent magnet generator for vehicles changes linearly with the increase of the engine speed, and cannot output To stabilize the voltage, the centrifugal permanent magnet generator needs an additional voltage stabilizing mechanism.

[0003] The Chinese patent variable air gap eddy current speed regulation induction motor (application number: CN200910025574.3) proposes an axially variable air gap eddy current speed r...
