Abstract

Hybrid excitation starter generator (HESG) has an increased number of magnetic potential sources, leading to issues such as complex magnetic circuits, numerous structural parameters, and low space utilization. These factors cause traditional analysis methods to have long cycles and low accuracy. In this paper, a new type of salient pole electromagnetic and permanent magnet composite pole HESG is proposed, and an analysis method combining hierarchical optimization and Taguchi method to analyze the influence of different structural parameters of composite pole rotor on the HESG performance is proposed. Response surface method was used to simulate the stator groove with multiple objectives, analyze the electromagnetic characteristics of HESG, complete the performance optimization, prototype, and conduct experiments. The results show that the amplitude of the air gap magnetic density base of HESG is increased by 7.4%; the distortion rate is reduced by 10.6%; the output voltage is increased to 127.68 V; the output performance and magnetization ability are significantly improved; and the overall performance of the HESG is improved.
