Abstract: Synchronous motors (SMS) continue to be a viable alternative to induction motors because of efficiency advantages. Since SMs have long been used to provide leading kvar for power factor (PF) improvement and to help with the device switching in load-commutated inverter (LCI) drives, these machines are efficient prime movers for large mill applications.

Synchronous motor - Wikipedia

A synchronous electric motor is an AC motor in which, at steady state,[1] 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 ...
