I recently assembled a 10 hp rotary phase converter with a proven design that I use. During commissioning I found that occasionally the idler would not start. Just sat there and hummed. I noticed that the idler was rotating counter clockwise. I changed wiring to have it rotate clockwise. The idler then started consistently every time. Should the idler always be wired to rotate clockwise. If this is so, it would be great to have someone explain to me, why. Cheers.
