I am having problems at my shop with a new to me clicker press (hydraulic press for die cutting). The seller assures me that the machine worked perfectly at their shop, but it does not seem to work correctly in my shop. Basically, the motor spins up fine (yes in the correct direction), but when I go to activate the press, it is really weak. I can barely punch through paper with a small die. I did keep a meter on the line to see if there is any droop in voltage, but it is rock solid at 208.
This is the second machine we tried with the same symptoms. The plate on the motor reads 220VAC 3 phase 60Hz, 1HP. I thought that there was a magical 10% rule on this type of motor so that they would operate from 200-240VAC? Any suggestions on options? The way I see it, I can either call the power company and see what my options are for getting 220 ($$$$ I am sure), or maybe a transformer setup. I called Grainger about it and they recommended PN 1H271, and two of them. How would this work? Wouldn't I need one on each leg? Thanks for any help!
