We have a moving shiploader boom with cover reels on both ends. As the boom shuttles through a cradle one reel pays out and the other reel pays in. We are trying to come up with a method to balance/control the two reel forces to not overpower the motor that actually pushes the boom.

Balancing Belt Tension
- Thread starter agrico
- Start date
controlling three motors simultaneously is trickly.
i think you could automatically control to two wire drum motors by adding a tension control. downstream of the motor put a fixed idler wheel. then add a tensioner arm between the fixed wheel and the motor. As the arm extends it increases the tension in the cable, similiarly as the tension in the cable increases the arm is moved. sounds like something you can control; no?

A controls solution is put encoders on the motors and drive them with programmable inverter drives. Then you could modulate each motor as desired with respect to the other via programming. Some drive vendors have built-in facility for reading other motors' encoder values. You might ask this question in the electrical motors forum. Them electron-chasers over there are smart and clever. Mostly.
