Design and control of a dual pole widths induction machine based on the Intelligent Stator Cage Drive Concept

Novel electric machine types with a high number of independent phases, such as the Intelligent Stator Cage Drive [1], enable new possibilities for rotor designs and thereby cause challenges for the machine control. One of the new potentials of these special multiphase designs is the possibility of operating with dual pole widths. This new type of operation mode for induction machines in connection with the ability to switch the number of poles while operating widely extends the operating radius, as it appears as a virtual gearbox in the traction drive. A dual pole widths induction machine will be developed and a control method will be presented.
