Claims (1)

[Claims for Utility Model Registration] (1) Two sets of brushes are provided on the bottom surface of the output gear, and one
One set of brushes has a limit switch mechanism that turns off the motor circuit to prevent further rotation at both ends of the rotation angle range of the air control door drive motor, and the other set of brushes has a limit switch mechanism that turns off the motor circuit to prevent further rotation of the air control door drive motor. In a motor actuator that has an absolute encoder that slides according to the rotational position of the output gear and outputs a stop position signal, an arc-shaped common conductive plate for stop signals formed in a comb tooth shape and a common conductive plate arranged on a radius line are used. and a stop signal brush constitute means for transmitting and generating a stop signal, and when the brush comes into contact with the common conductive plate, output signals of other absolute values have already been switched. Actuator. (2) The number of bits was increased by arranging the stop signal brushes along two radial lines, and by arranging the conductive plates for each signal, which were arranged independently, so that they did not overlap on one circular arc. A motor actuator according to claim 1 of the utility model registration claim.
