特徴とするモータアクチユエータの制御装置。 A motor M that is rotatably attached to the casing and drives an output shaft 2 whose rotational position is set in advance, a brush 4 attached to the output shaft 2, and sliding members 3a to 3g on which the brush 4 slides. Based on the rotational position detected by the detection means, the motor actuator MA includes a detection means for detecting the rotational position of the output shaft 2.
In a motor actuator control device that controls the drive power that drives the motor M, a first switch 12 is turned on when the output shaft of the motor M is rotated in one direction, and a first switch 12 is turned on when the output shaft of the motor M is rotated in the other direction. A second switch 13 that is turned on when rotating in the direction
Based on the timer 14 that detects that a preset predetermined time has elapsed, and the detection means, the current rotational position of the output shaft 2 is other than the preset rotational position, and the rotational position of the output shaft 2 is detected. When it is determined that there is an abnormality, the power supply to the motor M is temporarily stopped, and when the first switch 12 is turned on, the motor M is rotated in one direction for a predetermined time based on the timer 14. While outputting driving power to the motor M, when the second switch 13 is turned on, driving power is output to the motor M to rotate the motor M in the other direction for a predetermined time based on the timer 14.
1. A control device for a motor actuator, comprising control means 10 and 11 for outputting an output to the motor actuator.
