Modeling and Evaluation of CycloconverterFed TwoStatorWinding SAG ...

Abstract: Typical drive configurations of highcapacity SAG mills use a twostatorwinding vectorcontrolled synchronous motor, with a 30 ^{circ} shift between the two windings, fed by a twosecondary deltadeltawye power transformer and two sixpulse cycloconverters. This paper presents and evaluates three different modeling options for the SAG mill drive.
