NO, A 1840 ozin is BIG. so the numbers must be sorta jumbled. 1840
at stall? or continious? 68v/krpm is translated into 68 Volts per
1000 RPM to wind up the motor you'll need a few hundred volts.

Ask how much it weighs in pounds

The rate between the encoder and the servo drive on a gecko is
somewhere in the 250,000 rate so you can reduce quite a bit. I think
Rutex has a 1,000,000 rate.

big; you'll need some better numbers on the motor to give a estimate
on this.

I'm guessing that you need +5 Volts, is so take it from the PC.
