Roll Mill With Motor

Rolling mills are a type of metal forming machinery that process various metals through one or more sets of rolls to reduce thickness, create uniform thickness, imprint a design or compact loose material. 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.
