In this work is presenting a reactive homoheteropolar brushless synchronous machine (RHHBSM), with stator excitation destined to operate as low power generator in hydroelectric, or wind power stations, or as servomotor with reduced inertia. We proposed in this paper a modeling and a simulation method by electric-magnetic coupled network, based on the permeance network, 3D analysis with a specialized software and the machine's orthogonal model.One prototype machine has been studied. Within this paper, we make a comparison between the results obtained by modeling with the magnetic equivalent circuits, finite element method and experimental results.I.
