Description
technical field [0001] The invention relates to a rotating power supply, in particular to a magnetic-mixed dual-voltage intermediate-frequency brushless synchronous generator. Background technique [0002] With the rapid development of rare earth permanent magnet materials, rare earth permanent magnet materials have begun to be used in the field of motors. Permanent magnet generators made of rare earth permanent magnet materials have the characteristics of small size, light weight, and high efficiency. However, the load voltage of the electric excitation brushless generator is easy to adjust, the structure is complex, the volume is large, and the weight is heavy. According to the respective characteristics and deficiencies of permanent magnet excitation and electric excitation, a new type of mixed magnetic dual voltage intermediate frequency brushless generator must be studied. Contents of the invention [0003] The purpose of the present invention is to provide a mixed-m...
