| Bibliography: | To solve the brushless of some hybrid excitation permanent magnet machine, two kinds of hybrid excitation generators utilizing harmonic excitation were presented through applying the harmonic excitation to hybrid excitation generator. Structures and working principles were introduced, and the two kinds of harmonic excitation modes were compared and analyzed from five aspects which are the source and way of harmonic electromotive force, capacity of inducing electromotive force, operating efficiency, copper of winding, and convenience of regulation. The analysis results show that the hybrid excitation generator utili- zing the tooth harmonic excitation has more obvious advantages. Finally, one hybrid excitation generator u- tilizing the tooth harmonic excitation was made, and the experiments were carried on the generator. The experimental results show that the hybrid excitation generator has the wider adjustment of the air-gap magnetic field and the higher efficiency. XIA Yong-hong, YANG Yu-wen, XU Bo, LIU Jun-b |
