Mathematical model of a reactive homopolar synchronous machine with stator excitation

In this work is presenting a reactive homopolar synchronous machine with stator excitation (RHSMSE) destined to operate as generator of low and middle power or as servomotor with reduced inertia and high-speed. We proposed in this paper a modeling and a simulation method by electric-magnetic coupled network, based on the permeance network and 3D FEM analysis with specialized software. In this paper we make a comparative study between the results obtained with the method of finite elements and the results obtained from the magnetic equivalent method.
