NEMA17-02
The NEMA17-02 is a high-performance bipolar dualshaft stepper motor that is ideal for precise motion and positioning tasks. With shafts extending from both ends, it offers additional flexibility for mechanical integration and opens up more possibilities than traditional single-shaft stepper motors.
With 200 steps per revolution and a step angle of 1.8°, the motor enables finely graduated and controlled positioning. It is particularly well-suited for applications in the fields of automation, CNC, 3D printing, milling, and robotics.
With a holding torque of 0.46 Nm, the NEMA17-02 offers a solid power reserve for more demanding drive applications. The compact NEMA 17 design allows for easy integration into a wide variety of machines and structures.
A particular advantage of the double shaft is the ability to mount a component—such as an encoder—on the rear side. This makes the motor particularly well-suited for applications that require not only precise control but also additional monitoring of the motor's motion.
