17HS8401B Nema 17 42x42x48mm 1.7A Bi-Polar Dual Phase 1.8° Stepper Motor
17HS8401 bi-polar stepper motors are used very commonly in a lot of 3D printers and RepRap CNC machines. It can also be used in general control machinery, automation and robotics applications.
A NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (42.3 x 42.3 mm) faceplate. The motor conveniently connects via a typical 6 pin JST connector.
This unit comes with a 6-pin female JST to 4 pin female header cable.
