Research on voltage regulation range of the hybrid excitation permanent magnet generator

This paper proposes a new machine model, and a much more precise calculation method is adopted to calculate the characteristic of machine. The voltage regulation range of the hybrid excitation permanent magnet generator is studied by finite element method and magnetic field distribution of different stator yoke widths is calculated in this paper. In the paper the characteristic of no-load and on-load voltage of hybrid excitation permanent magnet generator is calculated and analyzed through tooth flux method. Harmonic excitation and the non-linearity of generator are taken into account basing on FEM in the method. The value and waveforms of the voltage can be calculated accurately by using this method. In the paper, not only is the result of no-load and on-load voltage of Hybrid excitation Permanent Magnet Generator calculated, also the diversified factors affecting the performance of the Generator are analyzed. Thus, a good method is supplied to design the Generator.
