Hello,
Although it has been a while, I have built I have built several RPCs and all worked well.
A friend bought a new lathe and asked if I could build a static phase converter for him. Although I never built a static converter, I said sure figuring it was just a RPC without an idler. . I took my standard RPC design and eliminated most of the components. In the end it was just a Steveco 90-65 potential relay & 300uF of run cap used as starting caps. I wired everything up the way I would for an RPC. When I gave it power, the steveco 90-65 potential relay chattered immediately so I didn't even try to close the lathe contactor. I didn't have the bleed resistors on the caps, but thought that would just prevent chatter on shut down, not chatter whenever it had power... My design is below, What did I do wrong?
Thanks,
-Joe
