Features:
Stepping motors come in a wide range of angular resolution.The coarsest motors typically turn 90 degrees per step,while high resolution permant magnet motors are commonly able to handle 1.8 or even 0.72degrees per step.With an appropriate controller,most permanent magnet and hybrid motors car be run in half-steps,and some controllers can handle smaller fractional steps or microsteps.
