Looks like this is the motor: http://www.cadcamcadcam.com/motorservoglobepm-dc.aspx Rating is 1.75 amps at 30 volts DC, with 20 oz-in continuous torque at 2800 rpm. Stall torque is 170 oz-in. So, IMService 1.75A x 30V = 52.5 Watts 20 oz.-in. / 141.6 = .141 Nm @ 2800 RPM 170 oz.-in. / 141.6 = 1.20 Nm @ Stall I'll tuck that away.
