In a stepper motor system, the rotor is moved by energizing the stator windings in a defined sequence. The phase sequencer function of a stepper motor controller determines or specifies what phase combination is required to achieve the next incremental motion. A very efficient method of realizing a phase sequence or function is disclosed. For example purposes only, a three-phase, half-step stepping motor sequence is assumed. The phase sequence for such an example is illustrated in Fig. 1.
