Stepper Motor 2 PHASE 4-lead Nema17 motor 42BYGH40 40MM 1.7A 0.45N.M LOW NOISE | Motors & Drivers

Description:

It is a simple 2 phases hybrid stepper motor. It features 3.5kg high torque output. It is applied in most CNC machine or 3D printer such as makerbot and ultimaker. If you want to make your own CNC or 3D printer, this motor is the most suitable one. Usually, a CNC machine requires 3 motors and a 3D Printer requires 4.

Trying to find the right stepper motor is not an easy job. For that reason, we highly recommened this motor to 3D printer community.

It comes with 4 pin JST connector which is compatible with ultimaker control board, the cable length is 50cm.
