Re: [CAD_CAM_EDM_DRO] Power for Bridgeport series 1 vert mill

Hi Robert

If the main transformers are the same as my UK spec BP, the answer is Yes.
BUT the spindle motor will need to be re-wired and matched to a VFD as this
is the only three-phase item on the mill. The spindle motor usually has nine
wires inside the wiring block (on the side of the motor) along with a little
diagram for the different connections for various mains voltages.

As for the main transformer, look carefully at the mains side - It should be
wired to just one leg of the incoming three phase. In which case, select the
correct connections on the primary for 220V. The terminals should be clearly
marked.

Regards,Paul.


P.S. If you are in any doubt. Please, PLEASE, call in a qualified electrician
to do the work.
