They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. Steppers are a special segment of brushless motors. They are purposely built for high holding torque. This high holding torque gives the user the ability to incrementally ? step? to the next position. This results in a simple positioning system that doesn? t
