Hello All!
I am involved in a retrofit of a long overhead chain conveyor (aprox. 1,5 miles) to replace 4 old and problematic DC motors connected in a single DC drive for a 4 new AC motors equiped with encoders and controlled by 4 inverters.
I noticed in field measurements that the old DC motors current are quite similar and the system chain tightener has almost no oscillations which means that the load is pretty well distributed.
I've read the chain conveyor posts here but I really don't believe that a simple "Load Sharing" operation will work without excessive movements over the conveyor chain tightener.
I would like to know if anyone have some experience about this kind of application, because the posts about it here here don't have the tests and results of their authors. I want to keep this post updated with our results.
I will be grateful for any help.
Mauricio
