I have an application where I have a 5HP TEFC Baldor running open loop from a Yaskawa V1000 drive.
At times due to environmental changes the motor slows to as low as 14Hz trying to maintain the proper flow of material. Well at these speeds it trips with an OL1 Fault. At this speed there is not enough HP to drive that belt and it will sometimes stall the motor before it trips..
My report stated that we simply have to change the gear ratio and get the motor into a higher rpm, or we need considerably more HP.
Mechanical guys suggest putting a Baldor TEBC Inverter duty Vector motor on this application. 1000:1 constant torque speed range, Of the same HP....
What if anything, is that going to accomplish? I mean Power is Power and Current is Current. I have a 5HP Drive topping out on current, the 5HP motor is demanding more than the nameplate FLA under these circumstances. Is a TEBC motor going to make any difference ?
