In this paper, a method is discussed for calculating the load saturation curves of the inductor machine. The theory has been verified both by comparison with actual tests under load, and by stationary flux measurements on a machine under simulated load conditions. Both checks showed good agreement between test and calculated values. For these tests a homopolar polyphase inductor-alternator was used. Flux readings under no-load and load conditions were taken by use of search coils and a flux meter. The method used to simulate load conditions is described in this paper.
