<P>PROBLEM TO BE SOLVED: To provide a phase adjusting method of a rotational position detector that can accurately perform the phase adjustment of the rotational position detector with respect to a rotating electric machine, and to provide a phase detector of the rotational position detector that can accurately detect the relative phase of the rotational position detector with respect to the rotating electric machine. <P>SOLUTION: The phase adjusting method of the rotational position detection of a reluctance motor comprises: a magnetization step that magnetizes a rotor having a plurality of salient poles; an induction voltage detection step that detects a temporal change of an induction voltage that is generated at a stator when the magnetized rotor is rotated; a rotational position signal detection step that detects a temporal change of a rotational position signal output by the rotational position detector when the magnetized rotor is rotated; and a phase adjusting step that adjusts the relative phase of the rotational position detector with respect to the rotating electric machine on the basis of a phase difference between the rotational position of the rotor introduced from the temporal change of the induction voltage and the rotational position of the rotor introduced from the temporal change of the rotational position signal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
