Modeling and Evaluation of CycloconverterFed TwoStator
Abstract: Typical drive configurations of highcapacity SAG mills use a twostatorwinding vectorcontrolled synchronous motor, with a 30° 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.
Voltage Sag due to Induction motor starting – Voltage
Apr 01, 2018 · Motor Starting Current: Induction motor starting on full voltage (also known as across the line starting or direct online starting) has the undesirable effect of drawing five to ten times or more of motor full load current.Usually this starting current of induction motor persists till the motor reaches close to its synchronous speed (rated speed).

Synchronous motor Wikipedia
A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line
