This NEMA motor meets all requirements. As a two-phase stepper motor it turns 1.8° per step and ensures smooth motion and an optimal holding torque of 3 Nm. With a feedback loop the motor controller detects and verifies that the number of steps is correct. It includes a sensor-equipped closed loop that improves positioning accuracy and prevents step loss within physical limits. Thus, this NEMA23 motor combines the advantages of stepper and servo motor technology.

Special feature: A closed-loop stepper motor driver is already included in the delivery.
