High quality 1.2A NEMA-17 precision stepper motor that is commonly used in 3D printers, CNC machines and other applications that require precise control.

Stepper motors draw power to hold their current position even if they are not turning, so they tend to be power-hungry.  They are best suited for being driven off a power supply rather than batteries unless you are using batteries with some serious current capability.
