Product description

NEMA17 stepper motors are the most popular motors used in the construction of 3D printers, milling machines, plotters and other electronically controlled devices.
The middle part where the coils are wound consists of a number of ferromagnetic plates connected to each other. Strong neodymium magnets ensure precise work. The kit includes 4 wires connected with a plug dedicated to stepper motors. On the other hand, the cable is terminated with a 4-pin pin plug, which allows direct connection to stepper motor controllers such as, for example, a set for building a RAMPS 3D printer or SHIELD for a CNC machine tool and many others.
