<P>PROBLEM TO BE SOLVED: To provide a technique for preventing plane mode oscillation by using harmonic components of lower order as much as possible, even if the plane mode oscillation of lower order is a problem because of the fact that the number of slots and the number of poles are approximate to each other, in a multi-slotted and multi-polarized axial-gap type rotary electric machine. <P>SOLUTION: The axial-gap type rotary electric machine wherein a stator 6 having a plurality of stator cores 8 wound with a coil 9 arranged in the circumferential direction and a multi-pole rotor 1 with a plurality of permanent magnets 3 are arranged facing each other in the axial O direction, comprises: superimposing means for creating single-phase or multi-phase alternating current by superimposing a plurality of frequency components comprising a primary fundamental wave component and a plurality of harmonic components each of which has a frequency of a multiple of the fundamental wave component and an order equal to the value of the multiple thereof, in the AC controller for the axial-gap type rotary electric machine for controlling single-phase current or multi-phase current flowing in the coil 9; and a frequency component control means for specifying the relation between the plurality of frequency components so as to arrange two sets of frequency component pairs different in the order by two. <P>COPYRIGHT: (C)2009,JPO&INPIT |
