Description
The Nema 8 Bipolar 1.8° 5.7oz·in 0.6A 6V Stepper Motor is a compact, high-precision stepper motor ideal for small-scale robotics, 3D printers, and automation projects requiring accurate control in a minimal form factor. With a step angle of 1.8° per step, it ensures smooth motion and precise positioning. Its bipolar 4-wire configuration allows easy integration with standard stepper motor drivers, while the high torque-to-size ratio makes it perfect for space-constrained designs.
The motor’s robust construction, D-cut 4mm shaft, and low operating current (0.6A) make it efficient and reliable for long-term use in precision applications.
