NEMA 17 High Torque Stepper Motor

The NEMA 17 High Torque Stepper Motor is a top-tier solution for applications that demand precise, repeatable movement and strong positional control. This motor features a step angle of 1.8°, delivering 200 steps per full rotation, making it ideal for CNC routers, 3D printers, robotic arms, and other mechatronics systems.

Constructed with high-grade copper windings and strong internal magnetic materials, the motor offers impressive holding torque to maintain position even without movement. Its compact NEMA 17 frame (42mm x 42mm) makes it versatile for integration into compact machinery, including DIY CNC machines and automation prototypes.

For advanced motion control, pair this motor with a reliable driver like the DRV8825 or A4988 Stepper Driver to unlock high-resolution, microstepping motion.
