Design, Analysis and Validation of a Six-Phase Induction Machine from a Commercial Three-Phase for Academic Research

Multiphase machines have been reemerged for high-power as well as fault-tolerant applications such as electric vehicles and wind turbines. Nevertheless, these types of machines are typically built only for industries for specific purposes. Therefore, the availability of multiphase machines in the market for academic research work, for instance at universities, is limited due to they require special construction processes and involve high initial costs for the companies. For that reason, the aim of this paper is to present a step-by-step design of a multiphase winding of an induction machine (IM) from a commercial three-phase IM for academic research use. The obtained results will be first analyzed by using the ANSYS Maxwell simulation environment. Then, a model-based current controller will be performed to validate the proposed design and the electric parameters of the six-phase IM.
