Continuous rated torque is the motor's continuous torque that it can output at rated speed, close to the max speed of the motor.This is a better judge of the motor's performance as it's the motor's torque at speed. Continuous stall torque is the motor's continuous torque at 0 speed (at stall). This is the locked rotor torque.

• ### What is Breakaway Torque? (with pictures) - wisegeek

Aug 19, 2019 · Static friction is the force that exists between two physical bodies to keep them from moving. For example, a wing-nut may have high breakaway torque because there is a lot of static friction between the nut and the bolt. If, however, the bolt is greased, the torque will be lower because the static friction has been decreased.
