I have a Rockwell Mill wiith the power table feed. The original feed controller is history. I purchased a controller from Beel Industries. The problem is the field of the motor is 60VDC and the Beel product puts out
90VDC. Instant short when voltage applied. If I back the input voltage down to ~60 VAC with a Variac all is well. No short or blown fuses, speed control works fine.I would like to eliminate the variac.
How is the best way to do it?
I've considered a step down transformer (220-110) hooked to 110. I don't know how the controller will like 60v in as far as power output (with the variac the motor was running free, no load) Or even if this will work at all.
A separate transformer for the field once I figure the current requirements with it's own bridge rectifier and then the controller run on 110 separately.
I've even thought about having the field rewound to 90v.
Other ideas?????
