A belt conveyor transports material 900 Tons/hr from a higher level to lower (130 meters). It is equipped with 2 motors of 132 kW 400V each. In the beginning motors drive the load and when material starts going down hill, the load is driving motors and the Motors RPM measured are 1509 against rated 1485 RPM.
Theoretically in this condition the motor is acting as generator and feeding power back to system. Someone suggested installing a regenerative drive for energy saving. However I think we will get no benefit as we are already getting power back in to system. Am I right? Or is there any advantage of using a pair of regenerative drives?
We have the budget but should we do it?
