Design and Analysis of a New Type of Parallel Hybrid Excitation Claw-pole Generator

Considering the disadvantages of the traditional hybrid excitation claw-pole generator, which easily causes irreversible demagnetization of the permanent magnet and relatively low utilization rate of the permanent magnet, a novel hybrid excitation claw-pole generator with Coordinate structure is proposed. In this paper, firstly, the structural characteristics and working principle of the new generator are analyzed and the equivalent magnetic circuit calculation model is established, and the influence of some parameters of the new generator on the output performance is analyzed through the equivalent magnetic circuit model. Second, the corresponding electromagnetic model is established by the finite element method to analyze the no-load magnetic field distribution and magnetic field regulation ability of the new generator. Finally, the calculation results are compared with the equivalent magnetic circuit model to verify the accuracy of the equivalent magnetic circuit model and provide a certain reference for the subsequent exploration and design analysis of the parallel new generator model.
