Powerful gears in rolling mills Machine Design

Most of the time, the gearbox operates at moderate load, usually less than 15% of the motor rating. But, when a bar enters the mill, the drive is subjected to a sudden, large momentary torque WEG mvw 01 medium voltage variable frequency drive The variable frequency drive can be used with high starting torque loads to control and limit the motor current. Energy saving is obtained with constant torque loads, since the absorbed power is directly proportional to the speed (P~N). Therefore, reduction on the speed results in Roughing Mill an overview ScienceDirect TopicsAssuming further that the efficiencies of the motor and the transmission are both 0.9, the total power to drive the mill is obtained, by Eq. (5.8), as 8170 kW. Using the same numbers and Eq. (5.9), the total power is estimated to be 5350 kW. The upper bound theorem, designed to give conservative estimates, also allows the prediction of the
