The present paper deals with the study and
experimentation of a rotor current excited Vernier reluctance machine.
First, the structure is introduced and the conditions on the teeth and the
polarity numbers necessary for the smooth running of such a structure are
presented. Then, a simple procedure is given, based on some simplifying
hypotheses, to obtain the initial geometrical and electrical sizes of a
designed prototype. To validate the operating principle of the structure, a
prototype is designed and studied using 2D FEM. Finally, this prototype was
constructed and simulation results were compared to those obtained from the
prototype.
