phase converter vs single phase
phase converter vs single phase
I design electrical systems for industrial machinery for a living and there is a reason commercial and industrial businesses use 3 phase; it is extremely robust and the motors virtually never need replacing. I understand that not everyone has 3 phase, so a single phase machine can do a good job, but with longterm hassles. I would not very use a motor above 7.5 hp, the efficiency drops off the chart and you are wasting money. Sometimes the best solution is a good phase converter. THey can be the weak link too, so get a good one. We spec American Rotary's digitally controlled rotarys into some of our equipment.
www.americanrotary.com They seem to be the most reliable and have the best voltage balance. Also very reasonably priced and being an engineer, I can actually talk to their engineers if I have a very technical question or requirment. Make sure you call and have the experts help size it. They have a database and most likely have experience with your specific machine.
The other option is to switch out the three phase components for single phase ones, but this is almost guaranteed to be more expensive and a big hassle.
