Yes. Our 2011 robot stalled two RS775 motors to hold our arm in position.
Doing math on the torque required showed each motor was only getting 6-7W of power, which is pretty darn safe.
Can't find the internal resistance spec for a 775 off-hand... You could take a multimeter to a 775 and measure the resistance, figure out a voltage that applies less than, say, 10-12W to the motor, and you're off to a good start.
