• Purpose In order to keep the advantages of PM generators and eleminate its disadvantage--difficulty in regulating the magnetic field, hybrid excitation is an effective way. This paper proposed a novel way to achieve hybrid excitation by use of tooth harmonic field. Design/methodology/approach Unlike weakening the tooth harmonics field and EMF in traditional machines, in this paper the tooth harmonics filed is proposed to form a novel hybrid excitation permanent magnet synchronous generator. Findings The generation mechanism of tooth harmonic electromotive force (EMF) of rotor winding is introduced, and its influencing factors are discussed in detail. The matching design of tooth harmonic winding and field winding for maximum output field current of tooth harmonic excitation system is analyzed. Practical implications This machine can achieve not only effective adjustment of the air-gap magnetic field, but also elimination of the brushes and slip rings.
