I am trying to use an AC servomotor in a winding application that will wind with constant tension.
I read somewhere that the way was constant HP but this makes no sense as current will be very very high at slower speeds.
I have also been trying to use the tension * radius = torque equation but can not get this to work either as test results show varying tension as the role gets bigger and as speed is changed.
I need to know how to calculate my current so that tension remains constant with increase in diameter and speed/rpm.
any insight here would be greatly appreciated
Thanks
