Kv 41 V / 1000 RPM, so at 2000 RPM it needs 82 V plus to get max torque it needs additional 8*8 =64V , so a 146 V supply will allow max torque at max speed. If the motor is really 0.8 Ohms, then it is 88 V. But, you probably don't need 2000 RPM. Even with a 2:1 belt reduction, 1000 RPM gives 500 RPM at the leadscrew, assuming 5 TPI that is 100 IPM.
