Modeling and Evaluation of Cycloconverter-Fed Two

Abstract: Typical drive configurations of high-capacity SAG mills use a two-stator-winding vector-controlled synchronous motor, with a 30° shift between the two windings, fed by a two-secondary delta-delta-wye power transformer and two six-pulse cycloconverters. This stone presents and evaluates three different modeling options for the SAG mill drive.
