ok, so the basic theory is that current = desired tension * radius / torque constant of the motor.
This is the equation that I used and when I changed the speed of the incoming paper, the tension changed considerably.
I then tested it at one speed and the tension was not constant as the role...
The motor is a baldor BSM90C-375
**broken link removed**
Everyone that I have talked to says that the torque and current are linearly proportional.
Im not sure what you mean in your statement about a VFD? Do you mean a variable frequency drive? If so, im not sure how a drive would do anything...
reel torque control
there is no mention of motor current in this document and that is what I am looking for, current as a function of radius and speed
I=f(r,s)
bsm90c-375
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...
