摘　　要：混合励磁电机不仅能继承永磁电机的诸多特点,而且电机气隙磁场平滑可调,电动运行时,具有起动转矩大、调速范围广的优点;发电运行时,具有较宽的电压调节能力或宽范围变速恒压输出能力,因此,具有广泛的工业应用前景。本文系统阐述了混合励磁电机的基本特点,并引入混合励磁及其混合励磁电机的基本定义,分析了混合励磁电机磁场调节的一般原理;对几种典型的混合励磁电机结构、原理以及混合励磁电机一般控制技术进行了分析,针对混合励磁电机设计、分析与控制技术的研究现状和存在的不足,探讨了混合励磁电机技术的发展趋势和研究方向。Recently, there is an increasing tendency to study hybrid excited machines（HEM）, which combine the advantages of PM machines with the controllability of magnetic flux by auxiliary field windings. The machine is essential for aerospace and electric vehicle application, etc. In this paper, the flux control principle of HEM is systematically introduced for the first time. The state-of-art of the machine topology, the design theory, and the control strategy are also overviewed. Finally, in accordance with the current problems of the HEM technology, some possible development trends of the HEM technology are discussed.
