Abstract
A one-phase electromagnetic motor drive controller includes a one-phase electromagnetic motor, a position detection mechanism for detecting a rotational position of the motor and a control mechanism for controlling the drive of the one-phase electromagnetic motor from the detected rotational position. When the torque constant of the motor is used as a parameter of a control calculation, the torque constant parameter is corrected by the relationship between it and the rotational position of the electromagnetic motor.
