On-Line Adaptation of the Rotor Time Constant for IM Drivesrough a model from the measurable terminal quantities of the motor and the speed (cf. Sect. .). The often used current-speed model contains the rotor time constant of the motor as an essential parameter whose exact knowledge influences decisively the quality of the control. This fact and the working

Their main advantage in this area is that the inverter in the rotor circuit can be designed to a smaller capacity with regard to the maximum generator output. Furthermore, the DFIM can be ran in a comparatively large slip range which

The interdependency of the concepts of magic (or, indeed, witchcraft, superstition, or even heresy) and religion or faith has been quite clear to scholars of early modern history. Historians have generally connected witch-hunts and the suppression of popular magic with the
