<P>PROBLEM TO BE SOLVED: To provide a control device of a motor which can reduce coil current variations caused by current harmonics which occur depending on a rotation position of a rotor of the motor. <P>SOLUTION: In the control device 100 of the motor, a current correction part 111 reads previous current deviations ed0, eq0, and previous current correction values ud0, uq0 which correspond to the rotation position θ of the rotor from a table stored in a table storage part 1111. Then, variations to occur in the coil currents i<SB>U</SB>, i<SB>V</SB>and i<SB>W</SB>owing to the current harmonics depending on the rotation position of the rotor of the motor are reduced by adding a value obtained by adding a multiple of the previous current deviations ed0, eq0 and a value obtained by adding the previous correction values ud0, uq0, to current command values req_id, req_iq. <P>COPYRIGHT: (C)2009,JPO&INPIT |
