A novel structure for vector control of a symmetrical six-phase induction machine with three current sensors

Vector control is one of the most popular multiphase induction machine drive methods due to its dynamic performance. In vector control drive, we need all phase currents; so with increasing in phase numbers, the number of required current sensors increases which is one of the disadvantages of vector control in multiphase machine drives. In this paper vector control of a symmetrical six-phase induction machine with novel configuration is discussed. The aforementioned configuration is designed in a simple way that only three current sensors will be needed. Simulation results are provided to verify the benefits of the proposed configuration.
