<P>PROBLEM TO BE SOLVED: To provide a motor controller which can prevent emergence of such a vibration mode as vibration of the rotor of a motor is excited. <P>SOLUTION: The motor controller 20 for determining the current values id and iq of d and q phases through dq conversion for converting the drive current of a motor M into dq rectangular coordinates and controlling a motor by performing current loop processing for each phase is provided with a means 26 for correcting the integration value fq in the q phase current loop by feeding back that integration value fq. Consequently, the emergence of a vibration mode exciting vibration of the rotor R can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT |
