Reluctance Generator (RG) can be operated at super high-speed because of its simple, robust rotor. Thus it is found acceptable for its high ratio of power/volume or power/weight as a small power source in airplanes, vehicles, etc., where electricity cannot be transmitted from external power source.While describing the output characteristics of RG, equivalent circuit or phasor diagram is generally applied. But although the iron and copper losses are caused by different mechanisms, they were treated by using a constant equivalent resistance in the past papers. In viewpoint of loss, it was same to that only the copper loss was considered. On the other hand, the iron loss is variable with the change of voltage and frequency. And the iron loss makes up the great part of the total losses especially when the machine driven at high speed. Therefore it is natural that the iron loss should be treated precisely.In this paper, the following points are discussed.(1) A new equivalent circuit with taking iron loss into consideration is developed by introducing an iron loss conductance. A measurement method (circuit diagram method) of the circuit parameters is also proposed.(2) The circuit parameters of the test machine are measured by applying the proposed circuit diagram method. And experimental results on the test machine show the validity of the new equivalent circuit.(3) Based on the new equivalent circuit, the relationship of the RG output characteristics and circuit parameters is studied. Thus the bases to choose the circuit parameters are given.
