PROBLEM TO BE SOLVED: To provide a motor drive controller, a motor drive control method, and a motor using them.SOLUTION: A motor drive controller includes a drive signal generating part, a counter electromotive force detecting means, and a control part. The drive signal generating part generates a drive control signal for controlling drive of a motor device. The counter electromotive force detecting means detect counter electromotive force generated from the motor device. The control part estimates drive current of the motor device using the counter electromotive force, and adjusts duty of the drive control signal when the estimated drive current corresponds overcurrent. |
