Synchronous motors Synchronous motors are usually of the low torque type in order to reduce the inrush current and the load of the mill drive train. A starting coupling is required to limit the motor torque during mill start. In the case of a high-speed synchronous motor a hydraulic coupling can be used. Low-speed low-torque motors
Due to the high torque required by the mill, low speed motors are generally synchronous machines. The mill is a low dynamic system therefore a brushless synchronous machine is best suited for this application. Brushless synchronous motors have no wearing parts, and the AC AC excitation power is kept small. The drive provides the

In synchronous motors the rotor rotates at the speed of stator revolving field. The speed of the revolving stator field is called as synchronous speed. The synchro-nous speed s can be found by the frequency of the stator input supply fs, and the number of stator pole pairs p. The stator of a three phase synchronous motor
Permanent Magnet Synchronous Motor PMSM Torque motors are generally PMSM motors that can be fitted with a closed loop control mechanism, like conventional servomotors. But the concept and shape of the high torque servo motor is different. A torque motor
mill drives and compressors. 17. What is slip The difference between the synchronous speed Ns and the actual speed N of the rotor is known as slip. 18. What are the various methods available for speed control of three phase induction motor Dec 2011 Nov 2015 Induction motors are of two types - Squirrel-cage motor and Wound-rotor motor.
Induction Motors AC slip ring motors are suitable for roughing and re-rolling mills where very precise speed control is not required. We can change the speed of the slip induction motor by introducing resistance in the rotor circuit. Slip ring motors are suitable for roughing stands of the rolling mill.
