Abstract:
A motor controller for correcting offset of a drive current of a motor. An offset amount calculating section (14) calculates offset amounts (Iuofs, Ivofs, Iwofs) of the drive currents (Iu, Iv, Iw) when the motor is being driven. A drive signal correcting section (18) corrects offset of the drive currents (Iu, Iv, Iw) by correcting the duty ratios of drive signals (Suo, Svo, Swo) based on the offset amounts (Iuofs, Ivofs, Iwofs).
