Abstract :
A field oriented control scheme is proposed, not requiring any shaft transducer. The flux-estimation problems in such conditions are considered. A suitable method is proposed and its theoretical limits are outlined. A prototype system has been implemented, on this basis, and the experimental results are given, confirming the practical feasibility for a wide field of applications.<>
