In a previous paper, we proposed a reluctance network analysis (RNA) model of a permanent magnet (PM) generator with a distributed winding and an overhang structure in which the permanent magnet is longer than the stator's stack in the axial direction. Using the RNA model, the basic characteristics of the PM generator were calculated accurately. A method for calculating the iron loss of the generator, however, was not discussed. In this paper, we estimate the iron loss on the basis of flux density waveforms calculated by using the RNA model. To verify the validity of the proposed method, the estimated values are compared with those given by a finite element method (FEM). In addition, we examine the accuracy of the flux and iron loss distribution obtained from the RNA model.
