I have the s on my Clausing 8520 mill (21/2" x 6" pulleys) and
on my Delta 14" Bandsaw (21/2" x 16" pulleys) I haves lots of torque even down to 100 rpm on the motor.
I can stall the bandsaw applying too much pressure.
I have two more of the same motors waiting to go on my lathes.

Hi, Ralph,
I realize that there would have to be gear reduction to at least a 2500 RPM spindle speed (assuming the desire to duplicate the original mini-lathe speed), but what I was speculating about was whether a Brushless DC motor, geared to 2500 RPM, would produce the same torque as a brushed DC motor geared to 1250 RPM.? I don't know; I have no experience with BLDC motors in lathes.? But the fact it they are used in the LMS lathes, which are quite nice in my view, would make me seriously consider them without a two-speed gearbox.
