摘　　要：永磁同步发电机结构简单、运行可靠 ,但是输出电压调节范围小。本文提出了一种解决永磁发电机电压调节问题的方法———利用永磁体和电励磁绕组组合励磁。这种发电机由永磁体和电励磁部分组成 ,发电机的主要气隙磁场由永磁体建立 ,电励磁部分提供电机调压所需的辅助磁场 。Permanent magnet synchronous generator has simple construction and operates reliably, but the regulating range of output voltage is small. In this paper, a new way that resolves the problem of regulating voltage by use of the combined excitation of permanent magnet and electrical excitation windings is presented. The generator is composed of the permanent magnet and electrical excitation windings. The field of main gap of generator is built up by the former, and the auxiliary field required when the voltage of generator is regulated is provided by the later. The two parts use one armature together.
