Comparative Investigation of Zero-Sequence Braking Torque in Six-Phase Induction Machines with Different Connections and Winding Designs
DC-signal injection into the secondary xy subspace is commonly used in multiphase drives for online stator-resistance estimation and winding-condition monitoring because it can be decoupled from the fundamental torque-producing excitation. Under open-phase post-fault operation, however, the post-fault current constrain...
