Patent ID: 7569999

Claim:
A motor control device for performing synchronous control such that rotational speeds and rotation amounts of a plurality of motors become equal, the motor control device comprising: a target speed generating unit for generating a generated target rotational speed; speed detecting units for detecting rotational speeds of each of the plurality of motors; an average speed calculating unit for averaging the detected rotational speeds of each of the plurality of motors to calculate an average rotational speed; a drive command value output unit for outputting a drive command value to each of the plurality of motors based on the generated target rotational speed and the average rotational speed; rotation amount detecting units for detecting the rotation amounts of each of the plurality of motors; an average rotation amount calculating unit for averaging the detected rotation amounts of each of the plurality of motors to calculate an average rotation amount; and drive command value changing units for generating a feedback signal for rotation amount control corresponding to each of the plurality of motors based on the average rotation amount and the detected rotation amounts, and changing the drive command value to be provided to each of the plurality of motors from the drive command value output unit based on the feedback signal.
