The 17HS4401-D is a standard Nema 17 stepper motor with a 40mm body, 1.5A rated current, and 40 N·cm holding torque. It is a common drop-in upgrade for 3D printers and CNC machines that use the 42mm form factor. Compared to smaller Nema 17 motors, it offers higher torque but draws more current, so check your driver and power supply. Owners often report it runs cooler and quieter than stock motors when tuned correctly.
