I didn’t see anyone else had posted this data…

I just checked the winding resistance on a room temperature NEO motor: 4.99 Amps produced 0.75 Volts. 0.15 Ohms from X to Y. This means that each coil is 0.225 Ohms. Just FYI, when I plug X into Y, I get quite a bit of drag torque and some cogging. With 5 Amps going from X to Y the motor holds position quite strongly; more torque than I was able to casually put on the shaft with my fingers.

Running the model, it looks like you might get 1.4 Nm of braking torque at full speed (5800 RPM) and **880** Watts of braking power going into the motor windings. There’s a very good chance that I’m calculating this wrong, though. I’m not 100% sure how to treat the shorted three phase windings. You REALLY don’t want to do that for very long! This braking torque tapers off as the motor speed falls, of course.
