【Abstract】 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.更多还原
