NEMA 17 bipolar stepper motor (ref. 17HS4401) delivering 0.45 N.m of holding torque. Ideal for 3D printers, CNC machines, and laser cutting projects.
The 17HS4401 is a bipolar stepper motor in the standard NEMA 17 form factor, designed to deliver reliable holding torque of 0.45 N.m. With a step angle of 1.8° and a rated current of 1.7 A per phase, it serves as a robust choice for precise positioning and automation tasks.
This motor is particularly well-suited for 3D printers (RepRap style), CNC machines, as well as laser or plasma cutting systems. Its 40 mm body length allows for easy integration into standard frames while maintaining low rotor inertia (54 g·cm²) for responsive dynamics.
