Re: synchronous motor



Original poster: penny831@xxxxxxxxxxxxx Speaking of Synchronous motors, can anyone advise me on how to hook up a teletype motor? It has two black leads and two red ones as well an additonal two black ones for a capacitor I believe. I also need to find a good value for the starter capacitor. Any advise????
