特徴とするモーターアクチユエータ。 A disk-shaped printed circuit board with a limit switch pattern that prevents rotation beyond a certain angle, two diodes that regulate the direction of current flow, and an absolute value encoder pattern is attached to the bottom surface of the output gear that is linked to the motor. Attach each to
Brushes for the limit switches are provided independently facing the disc-shaped printed circuit board, and the brush for the most significant bit of the absolute value encoder and the brush for the next most significant bit are placed on the same circumference of the output gear shaft. A motor actuator characterized in that the absolute value encoder patterns are arranged at a certain angle so that a part of the pattern for the absolute value encoder can be shared.
