When I first posted the qdd100 beta on mjbots.com, I performed a simple “continuous torque” test where I measured the torque that could be applied indefinitely without thermal limiting in a lab environment. It has come to my attention that other servos rate their “continuous torque” for a much lower value of “continuous”, sometimes only 30s. To make the situation clearer, I measured the time to thermal limiting at a range of torques and updated the product page.

For this test, at each torque value I started with the qdd100 in thermal equilibrium with an ambient 20C lab environment, then applied the given torque and waited until thermal throttling set in. No forced airflow was present and no conductive or radiative cooling enhancements were used.
