Anyone got a good online source for the calculations/plans on phase converters made from 3 phase motors?
The place I work at part time uses a phase converter built by a guy. It is a small unit based on a 1.5 HP motor, time delay, 2 start capacitors, and 2 contactors. We need a larger unit and have a 20 HP motor for the purpose but the guy that knows about it health has declined and is not able provide info, but I should know these things anyway.
I did use google but was hoping someone here could point me to a good source.
