Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a rare earth generator single-phase voltage regulating winding. Background technique [0002] Generally, rare earth generators use sinusoidal windings in order to improve the voltage waveform stator windings. Using this winding can make the waveform distortion rate of the output voltage less than 10%, which is better than ordinary small single-phase electric excitation generators, but it still cannot meet the waveform distortion rate. Users with higher requirements. [0003] Generally, the steady-state voltage adjustment rate of rare earth generators is about ±10%, which cannot meet the requirements of most users, and limits the popularization and application of rare earth generators. Contents of the invention [0004] The object of the present invention is to provide a rare earth generator single-phase voltage regulating winding. [0005] A rare-earth generator si...
