Having problems with a DC Drive Older BBC Veritron 10 hp that is running a 10 hp motor through a gearbox 5:1 ratio and drives a conveyor flat belt.
It seems the drive has no "balls" when the load increases on the belt and just stops. after a few minutes then it will trip the overload which I believe is on the armature leads (only one) I replaced the motor, checked the gearbox, and inspected the bearings on the belt it drives. I get no fault at drive or at least nothing I can see. Is it possible the drive is just failing (30 years) I am getting one in hopes of solving this but still am not convinced its the drive. Motor does not get hot, when gearbox is released from belt it will run with no load.
Any Ideas, Thanks
