I'm just wondering here, how else could you wire it in a three wire control. I have ONE hot wire (black), a blue and a green wire going to the stop/for/rev switch. I would assume one of the secondary wires coming out of the transformer would go to that black wire to feed the switch, do I just cap off the other secondary wire in the transformer and let it hang?
Another thing I've been wondering about. This drill motor was wired for high voltage where it lived at before and ate real 3 phase power for work done. I had to wire it for the lower voltage which the motor plate says 208/ 230v ac. that is now eating 240v ac.+/-, of not so clean 3 phase power. When I rewired the motor to low voltage would there be any changes needed at the motor starter wiring or any other place connected to the drill motor that would need to be rewired? Other than of course changing the heaters to a higher rating.
Anyway, just for no other reason other than being impatient an possibly a little dumb to boot I tried hooking it up the way I was talking about above. One side of the secondary I hooked up with the black feed wire going to the start stop switch and I drilled a hole in the side of the motor starter box where I screwed in a GND screw and connected the second, secondary wire to it. Turned the RPC on and operated the stop/for/rev switch to see what would happen and it basically did the same thing. the coils would not lock in but would just kick in and out like before. I could hold them in and hold them in by hand and the motor would run okay for awhile. I checked the voltage to the coils and now there is right at 114v ac at each coil when hooked up this way. When running the motor sounded the same as before, nice and quiet with no bings, bangs, or bellowing smoke anywhere. Right now I'm thinking both of the coils are bad, could that be possible?
