This NEMA motor satisfies any requirement. As a cloosed-loop stepper motor with 2 phases, it turns 1.8° per step and ensures steady movement and an optimum holding torque of 3 Nm. The feedback loop allows the motor driver to recognize and to ensure that the right amount of steps was taken. It contains a cloosed loop with a sensor which enhances the accuracy of positioning and prevents, in the scope of the the physical capabilities, the step loss. Thus, this NEMA23 combines the advantages of the stepper and servo motor technology.
