Expanding and upgrading. Looks like I'll have 5 auger motors and a dryer that will or could be 3ph. Dryer for sure is. I'd like to run the auger motors with speed control. If I did the math correctly I'd need a 150 horsepower phase converter. Question is how could I go about it. 1ph into phase converter then 3ph to vfd's for motors and 3ph to dryer. Or 1ph into converter for dryer and 1ph to 3ph vfd's for the motors. I have asked a few electricians and gotten different answers. Looking for real world advice. I believe the cheapest route is a phase converter with vfd's after it. None of these auger motors will run unless dryer is running. Fans and unloads are additional and can be run single phase although I may run unloads on 1ph to 3ph vfd's.
150hp seems like a huge draw on a single phase line.
If it all only runs when the dryer is on, why aren’t these kind of setups put together with a three phase propane or NG genset with the radiator air and exhaust ducted toward the dryer fan intake? You’d get the power you need and recycle the waste heat to where you’re going to be burning fuel to make heat anyway.
