Stepper Motor Nema 17 JK42HS48-1684-08AF Shaft-Reversed Stepper Motor

This is a shaft- reversed stepper motor that is frequently used in CNC machines and 3D printers.

The Advantages of step motors are low cost, high reliability, high torque at low speeds and a simple, rugged construction that operates in almost any environment. They are typically digitally controlled as part of an open loop system for use in holding or positioning applications.

This is a Nema 17 stepper motor with a 1.7 x 1.7 inch (43.2 x 43.2 mm) faceplate. The Nema 17 is larger and generally heavier than for example a Nema 14, but this also means it has more room to put a higher torque. However, its size is not an indication of its power.
