<P>PROBLEM TO BE SOLVED: To provide a motor which can reduce the vibration of a stator by offsetting it by the electromagnetic force generated by a high frequency current. <P>SOLUTION: In a motor which is equipped with a rotor having eight pieces of magnets and a stator having forty eight pieces of teeth 1, 2, 3, 4, 5, a motor control current where an AC current AC<SB>-</SB>H of high frequency having frequency of the eighth rotation is superposed on an AC current for generation of a rotating field is supplied to the coil of the stator, and exciting force KP<SB>-</SB>48 having the forty eighth rotation degree applied to each tooth 1, 2, 3, 4, 5... is offset by electromotive force EMF<SB>-</SB>FT. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
