Hi All
This discussion on motors in tandem, is quite opportune as I am currently battling with a conveyor belt application where a 4M wide 1200M long belt driven by 4 motors using scoop actuated
fluid couplings (which when fully engaged) uses almost twice the KW in 2 of the motors, as it does in the other 2. Can anyone direct me to a source of information on this subject, or perhaps offer an explanation as to why and how to control this.
My current project deals with control of the scoop actuators using a PI controller and an enertron KW transducer, the idea is to bring in
the scoops in such a way as to share the load evenly between the 4 motors, allowing each motor to catch up to the average of the 4 motor feedbacks, before the next setpoint step is issued. This however seems a little futile, if the motors will never do the same work during fully laden operation.
Thanks
