<P>PROBLEM TO BE SOLVED: To provide a motor controller capable of suppressing fluctuations in torque. <P>SOLUTION: The motor controller includes an inverter 30 for generating a plurality of phases of sinewaves (Iu, Iv, Iw) by controlling a plurality of switching elements (T1, T2, T3, T4, T5, T6) with PWM; a motor which generates a rotating field in a stator coil by supplying the generated sinewaves (Iu, Iv, Iw) to the stator coil, and which permits a rotor to be rotated and driven by the operation of the rotating field; a storage device 25 for detecting the sinewaves (Iu, Iv, Iw) of each phase generated in the inverter 30, and for storing the amount of correction of each phase calculated so that the sinewaves (Iu, Iv, Iw) of the each phase match each other on the basis of the detected result; and a corrector 24 for correcting PWM signals which control the switching elements (T1, T2, T3, T4, T5, T6) with the PWM on the basis of the amount of the correction. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
