17HS4023 Nema 17 42x42x24mm 0.7A Bi-Polar Dual Phase 1.8° Stepper Motor (Pancake Motor)

17HS4023 Nema 17 42x42x24mm 0.7A Bi-Polar Dual Phase 1.8° Stepper Motor

17HS4023 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.
