Patent ID: 8680807

Claim:
A motor control apparatus for controlling a DC motor, the motor control apparatus comprising: a first detection unit configured to detect an angular velocity of the DC motor; a driven member configured to be driven by the DC motor; a control unit configured to perform, during start-up of the DC motor, feed forward control for changing a control value used for controlling drive of the DC motor from a first control value corresponding to an angular velocity lower than a target angular velocity to a second control value corresponding to an angular velocity higher than the target angular velocity, and to change the feed forward control to feedback control to keep the DC motor at the target angular velocity; and a second detection unit configured to detect whether the driven member is replaced, wherein the feedback control generates the control value based on a third control value obtained from a result of the detection by the first detection unit and the target angular velocity, and a fourth control value, and wherein if the second detection unit does not detect replacement of the driven member, the fourth control value is set based on the control value generated by the feedback control performed in a previous driving of the DC motor, and if the second detection unit detects replacement of the driven member, a predetermined control value corresponding to a replaced driven member is set as the fourth control value.
