Continuous Regenerative braking of a downhill conveyor
Continuous Regenerative braking of a downhill conveyor
(OP)
How can I use regenerative braking continuously. I have a stacking conveyor that that wil be running down hill and then gradullay luffing up as we fill a dam with concrete.
I want to use regenerative braking continually (24hrs a day) for the first 6 months as the weight of the load will drive the conveyor down. Speed control isn't critical as the whole system will be working at one speed but I want to control the speed of the luffing conveyor to match the other conveyors
After 6 months the conveyor will be driven as normal for a total of 2 years. Hence the option must also be cheap.
It is my understanding that standard drives do not like being driven in this mode of operation on a continuous basis. Please advise

This may not be the cheapest to install, but I believe will have the lowest overall price (design, install, maintain, control, operate).
Such a unit works in a cement factory for several years now, 24/7, controlling a several 100's HP blower motor ramping up and down all the time to keep a control set point.

The regeneration system is connected to mains power lines to supply the network when regenerating.
If mains supply disappears for any reason, you will have NO BRAKING!!! You will need powerfull emergency braking/holding drum to kick in on mains failure.

If you wanted to go DC any old regenerative DC drive would be able to do this. Only problem is, the plant power factor takes a hit.
