<P>PROBLEM TO BE SOLVED: To provide a motor drive controller improved in rotation performance and response characteristic of a final driving target. <P>SOLUTION: The motor drive controller 10 for controlling the rotation speed of a motor is provided with: a motor driver 11 for rotating and driving the motor 12; an FG sensor 13 for detecting the rotation speed of output of the motor 12, and a correction coefficient calculating unit 71; an encoder 15 for detecting the rotation speed of a photosensitive drum 43 rotating on a rotation driving force of the motor 12, and a correction coefficient calculating unit 71; and a control section 100 for generating a speed control signal corresponding to a value calculated by using: the information about the rotation speed of the motor 12 based on the outputs of the FG sensor 13 and the encoder 15; and the information about the rotation speed of the photosensitive drum 43, and for outputting the generated speed control signal to the motor driver 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
