Re: [CAD_CAM_EDM_DRO] Re: Bridgeport motor question

Hi Tim

IF you are sure this is the Star point, split it up and hook a wire to each
winding - Bring the three wires out via the existing terminal housing.
Two things to bear in mind - 1) Use suitable flexible wires. 2) Use high
temperature sleeving, not heat-shrink or sticky tape to insulate any joints
inside the motor.

Speed control is done via a 0-10V DC signal for which a DAC output is
required. An alternative would be to pre-set three speeds and use the digital
inputs that are normally used for On/Reverse/Jog functions.

Regards, Paul.
