Single-phase multifunctional rare-earth permanent magnet generator

Abstract

The invention relates to a single-phase multifunctional rare-earth permanent magnet generator, mainly consisting of a shell, a stator, a rotor, an inverter and a control system. The stator comprises a stator iron core and an armature winding; the stator iron core is repeatedly pressed into a chute by stator punching, and the armature winding adopts concentric windings with different turns; the rotator consists of a rotating shaft, a cylindrical magnetic-permeability yoke and paired tile shape magnetic steels which respectively fix N pole and S pole respectively on the excircle of the magnetic yoke; and the control system consists of two circuits. The single-phase multifunctional rare-earth permanent magnet generator not only has the characters of small volume, light weight, high efficiency, simple structure and reliable operation, simultaneously overcomes the defects that the permanent magnet is difficult to adjust magnetic field to control voltage from the outside so as to cause that the voltage stability is poor and the waveform distortion factor is large, also can automatically switch to a first circuit of the control system for supplying power continuously when the inverter fails, realizes multifunctional and continuous power supply with more reliability and has outstanding practical value.

Description

Technical field: [0001] The invention relates to a rare-earth permanent magnet generator, in particular to a single-phase multifunctional rare-earth permanent magnet generator, which belongs to the field of motors. Background technique: [0002] The existing rare earth permanent magnet generator uses rare earth as the permanent magnet as the magnetic source of the generator to replace the magnetic field coil of the electric excitation generator, and can be made into a brushless generator, eliminating the need for slip rings, brush devices, power capacitors, Electronic components, etc. Therefore, it has the advantages of small size, light weight, high efficiency, simple structure, and reliable operation. It is the development direction of the motor field, but there are also defects that it is difficult to adjust the magnetic field from the outside and control its output voltage and sinusoidal voltage waveform. At present, most of the rare earth permanent magnet generators ar...
