The application of a vector controlled AC drive for internal batch mixing of rubber compounds

Abstract

The mechanism of processing rubber compounds in an internal mixer creates a tough, demanding application for which a vector-controlled AC variable frequency drive was found to be eminently suitable. A 1500 hp, 2300 volt, current-fed inverter was successfully applied to this common industrial process. A description is presented of the control strategy, drive construction and operation, and application considerations. Operating results are discussed.<>
