<p>A motor controller for correcting offset of the drive current of a motor comprising an offset calculating section (14) for calculating the offset amount (Iuofs, Ivofs, Iwofs) of the drive current (Iu, Iv, Iw) when a motor is driven, and a drive signal correcting section (18) for correcting offset of the drive current (Iu, Iv, Iw) by correcting the duty ratio of drive signal (Suo, Svo, Swo) based on the offset amount (Iuofs, Ivofs, Iwofs).</p> |
