I believe it uses standard BT40.

I bought my maintainance manual direct from hardinge bridgeport leicester (uk) for approx $140 dollars.

I'm re-using the existing spindle motor. Just paid about $1600 to get it running. This included a complete clean out, skimming & undercutting of the comm, new motor brushes, new taco brushes, a 5kw autotransformer, a PWM dc motor driver and, single phase conversion for the blower motor and a small variac for the field windings.

Its quite a comlex setup but it would have cost 3 x more to replace it with a new AC motor.
