<P>PROBLEM TO BE SOLVED: To provide a motor control method which can control a complex current generated by a rectangular wave voltage, for a complex current comprising low frequencies and high frequencies, using a normal two-level inverter. <P>SOLUTION: In the control method of an AC motor which comprises at least one rotor and is driven by superimposing an AC current of at least two frequency components, at least a pulse voltage of the number of the frequency components is outputted into one of AC frequencies, each pulse phase is operated by being synchronized with each of a plurality of the frequency components, and the AC current of the plurality of frequency components is generated. <P>COPYRIGHT: (C)2008,JPO&INPIT |
