Stepper Motor Voltage Explained
Stepper motor ‘voltage’ is an often confusing subject. Many motor drivers use widely varying bus voltages to operate stepper motors. In fact, identical stepper motors can be (and commonly are) operated at greatly different voltages in different systems. How can the same motor be run at different voltages? How does the bus voltage impact the stepper motor’s performance?


The 3-phase stepper Motor offers a middle course between the 2-phase stepper motor (standard) and the 5-phase stepper motor with a very small step angle and low vibrations. These 3-phase stepper motors are widely used on small to mid-sized CNC milling machines, CNC lathes, Pick-place machines, Laser Engravers, Laser Cutters, and CNC Plasma Cutters.
