Stepper motors divide each full rotation into a number of equally sized steps. Also known as step or stepping motors, these 2-phase brushless DC motors offer quick, precise load positioning and exceptional holding torque at any of these incremental steps. Each step represents 1.8°, or 200 steps per revolution. When using a microstepping drive, each 1.8° step can be broken into even smaller increments to achieve nearly servo-like positioning performance—without the need for complex feedback devices or a closed-loop control system.
