Abstract: There is provided a motor control device for an actuator having a motor, including a measuring unit configured to measure a temperature of the actuator or a temperature corresponding to the temperature of the actuator, a determining unit configured to determine whether the temperature measured by the measuring unit is lower than a preset temperature, and a boost control unit configured to perform boost control at activation of the motor to increase drive power supplied to the motor if the determining unit determines that the temperature measured by the measuring unit is lower than the preset temperature. The boost control unit is configured to perform the boost control such that, only within a boost period after starting activation of the motor, drive power larger than that supplied to the motor during steady driving after the boost period is supplied to the motor.

Abstract: There is provided a motor control device configured to control an energization state of a coil of each phase for driving a stepping motor having multiple phase coils. The motor control device includes a measuring unit configured to measure a back electromotive voltage induced at a coil of a phase for which energization is stopped, among the multiple phase coils, an acquiring unit configured to acquire temperature information on temperature of the stepping motor or on temperature corresponding to the temperature of the stepping motor, and a detecting unit configured to detect whether the stepping motor is out of step or not based on a result obtained by the measuring unit and the temperature information acquired by the acquiring unit.

Abstract: There is provided a motor control device controlling an energizing state of a coil of each phase for driving a stepping motor having multiple phase coils. The motor control device includes a detecting unit configured to detect whether the stepping motor is out of step, and a reverse rotating unit configured, when the detecting unit detects that the stepping motor is out of step, to rotate the stepping motor in a second rotation direction reverse to a first rotation direction, which is a rotation direction of the stepping motor before detecting out-of-step, by a number of steps with which a stress received by the stepping motor is alleviated, before the stepping motor spontaneously rotates in the second direction.
