To rotate the shaft of the stepper motor, a sequence of pulses is needed to be applied to the windings of the stepper motor, in a proper sequence. To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for The stepper motor has rotor teeth. To get absolute address, all remaining address lines A 15 — Iterfacing 2 are used to decode the address for With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x.
It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors. The 82555 of pulses can be decided, depending upon the required motion of the shaft. Feedback Privacy Policy Feedback.
