I'm slowly gathering all the bits I need to convert my BF46 to CNC, one feature I want is rigid tapping and to be able to thread mill.

While the existing spindle motor is a DC motor I have been thinking of fitting a servo to power the spindle, what would people recommend for this?

I found a 3kw 2500rpm servo on ebay New AC Servo Motor Drive Kit 3PH 220V 130mm 13 5nm 3KW 2500rpm 13 5A 3M Cable | eBay would this work as a spindle motor?
