I'm puzzled again...
I'm reworking a Millrite with Z and X powerfeed. I've replaced the bevel gears in the knee, freed up the rust parts that are supposed to move and replaced the Z drive motor. The head and original Z drive motor were all 3 phase. Near as I can tell these 3phase was all that was fed into the machine. The main junction box fed directly into the old transformer box. Thus, 3phase to the transformer.
The DC X axis motor is getting a complete rewire by a DC motor guru.
The transformer and box appears to have suffered significant internal heat.
Thus, a new box and transformer.
However, how do I hook this up to 220v 3 phase? Where does the third incoming leg go? Looks like I jump H1 and H3 and connect to incoming Line1. And jump H2 and H4 and connect to Line 2. Where does the third Line 3phase leg go? I didn't have much to start with when I got this trauma victim.
I need 1110v 1phase out to the DC motor.
The first pick is a close up of the old transformer, the second pic is the new.
Thanks all for your ongoing patience!
