Abstract:
A method for correcting the balance of an inner rotor type scanner motor, comprising the steps of:separating said scanner motor into a rotary part, which includes a motor housing having a bearing for supporting a rotating member to which a driving magnet is fixed, and a stationary part including a stator coil and a magnetic member fixed on a base;mounting the separated rotary part on a balance corrector, which includes a stator portion having a substantially identical structure to the said stationary part of said scanner motor;measuring an amount of unbalance of the rotary part of the scanner motor while rotating the rotary part on the balance corrector; andcorrecting the balance of the rotary part of the scanner motor according to the amount of unbalance of the rotary part in a state mounted on the balance corrector.
