摘要/Abstract

摘要： 克服普通开关磁阻电机（SRM）固有缺陷，提出了一种混合动力汽车皮带式驱动起动/发电机（BSG）用新型容错式分块SRM，并分析其电磁特性。为提高容错式分块SRM的输出转矩，对影响电机输出转矩的关键结构参数进行优化处理，分析优化后电机的静态特性和动态特性。为研究分块SRM的容错性能，对比分析普通SRM和优化后分块SRM的互感和缺一相故障下的电磁特性。设计并制造出一台试验样机，对样机开展静态特性和负载运行的试验研究。仿真和试验结果表明，优化后的分块SRM输出转矩更大，比普通SRM的动力性能和容错性能更好。通过对新型容错式分块SRM进行优化和容错性分析，为设计安全可靠的BSG用电机提供了理论指导。

Abstract: To overcome the inherent defects of conventional switched reluctance motor (SRM), a new type of fault-tolerant segmented rotor SRM for the belt-driven starter generator (BSG) of HEVs is proposed, and then its electromagnetic characteristics are analyzed. Firstly, in order to improve the output torque of the new fault-tolerant segmented rotor SRM, the key structural parameters affecting the motor output torque are optimized, and the static and dynamic characteristics of the optimized motor are analyzed. Secondly, to study the fault-tolerant performance of the proposed motor, the characteristics of mutual inductance and fault tolerance features in case of a phase failure of the conventional SRM and fault-tolerant segmented rotor SRM are compared. Finally, an experimental prototype is designed and fabricated to verify the static characteristics. In addition, experimental studies on the prototype motor were carried out when it operated under the load operation. Both the simulated and experimental results reveal that the output torque of optimized fault-tolerant segmented rotor SRM was larger than that of the motor before optimization. Moreover, its dynamic and fault tolerance performances were better than those of the conventional SRM. Through the optimization and fault tolerance analysis of the fault-tolerant segmented rotor SRM, theoretical guidance for the design of BSG motors with safe and reliable characteristics is provided.

Key words: BSG, fault-tolerant, HEV, mutual inductance, output torque, segmented rotor SRM
