sugar mill drives - sasta

A large variety of driven machines are to be found in a sugar mill-fortunately these drives fall into only three basic types, viz.,. (I) Constant speed,. (2) Variable speed over a wide range,. (3) Variable speed over a limited range. In most mills the constant speed drives are accom- modated by electric motors while steam units.

Drive selection for rolling mills - Russula

May 20, 2010 . Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800rpm to be cost effective. Also the case for higher efficiency of AC motors is many times negated by the wasteful braking methods of some AC drive systems. All this being said, for motors.

Which motor is used in rolling mills? - Quora

I've been in a Kawasaki steel mill outside Osaka, that uses large induction machines with Mitsubishi 3,300v, IGCT-based VFDs that have replaced the previous DC machines . Mitsubishi used this facility to show the control ability of their drives and the size difference of the induction machines (about one-half the footprint).
