Servos for CNC Bridgeport mill

On a mill that size I have used 1.5kW low speed servos (1500rpm)
It was roughly the weight class as yours but with a 7.5hp spindle.
I also used a fryer mb-14? (20x40) mill as reference and it had 1.3kW servos.
Both the fryer and the other mill were about 8k lbs weight. A 3k Bridgeport with a 3hp spindle would only need about half the kW with a 2:1 timing belt drive like you see on prototracks.
Our axis servos were direct drive to the screws.
