NEMA23-04CL
The NEMA23-04CL is a high-performance bipolar stepper motor with closed-loop control that combines the advantages of traditional stepper motors with position feedback. An integrated sensor monitors the motor's actual position, helping to minimize missed steps and improve positioning accuracy.
With 200 steps per revolution and a step angle of 1.8°, the motor enables precise and repeatable movements. Thanks to its closed-loop control, it is particularly wellsuited for applications that require high reliability and precise positioning.
The high holding torque of 3 Nm provides a substantial power reserve for demanding automation, CNC, and robotics applications. At the same time, the control loop’s feedback ensures that the actual motor movement can be monitored—a decisive advantage over conventional open-loop stepper motors.
With its robust NEMA 23 design and separate connection cables for the motor and control circuit, the NEMA2304CL can be flexibly integrated into performanceoriented machine designs. This makes it particularly well-suited for applications that require a combination of high force, precision, and process reliability.
Special feature: The closed-loop capable stepper motor driver is already included in the delivery.
