Turning next time needs the polarity of alternating voltage applied.For example, determine rotor magnetic pole position belong in Fig. 5 a) to feelings c)
Under condition, the polarity of alternating voltage for judging to need to apply next time is negative polarity (negative half period)；And determining rotor magnetic pole position
Belong to the d in Fig. 5) to the polarity of alternating voltage in the case of f), then judging to need to apply next time for positive polarity (positive half cycle).
