With the givin information I need to be able to determine the correct freq. for the VFD to run at to achieve a certain line speed. Here's the information:
Motor operating at 60 Hz has RPM of 1180
The Gear Box has a 159:1 ratio
The Drive sprocket on the gear box is a 13 tooth
The Driven sprocket has 19 a tooth
The net line speed for the sprocket pulling the 2 strand conveyor link off of the Driven is 67 Jobs per Hour
What is the freq needed for this line speed.
I keep tweaking the formula for each new freq but this results in a fractional number of poles for the original motor when compared to the actual conveyor found in the field. I think I just need a new perspective for this equation...
