Re: [CAD_CAM_EDM_DRO] Brushless Servo Motor Drivers

Is this 20 A x 120 V = 2.4 Kw ?
Sounds like just the ticket for my lathe.

I will see how it goes with my trials, and may order one from You if the
treadmill ones don´t do it.

Any re: on a motor?
I am aiming for best bang/buck, as near max power as possible, for a
decent price.
Original motor is AC 1.5 kW, so something around this, or a bit more.

Should it be ok on a 10k us digital encoder ?
