This paper deals with the generation of optimal current references for Multi-phase Permanent Magnet Machines with open-circuited phases. Compared to classical methods, the use of a vectorial approach makes it possible to generate optimal current references, from a copper losses point of view, on-line. This method is viable whatever the number of open-circuited phases. As an example, a five-phase machine is experimentally controlled.
