If the stator phases are excited in the sequence A-AB-B-BC-CA-A (shown in Table 4.6), i.e., alternately in the one-phase-ON and two-phase-ON modes, then it is sometimes known as “wave” excitation and it causes the rotor to advance in steps of 15°.Table 4.6Half-step operation one-phase-ON and two-phase-ON mode “A-AB-B-BC-C-CA-A”
