Motor will be used for Pipe Bending
I am using a GB of 70:1 ratio
Max. Emergency Torque of GB is 1260 n.m,
You can find, i think, the datasheet of the motor at the web site of the manufacturer.
Also,I think that a permanent magnet motor has a constant torque, regardless of the speed: the curve of the power output regarding rpm is a straight line with a constant slope.
