<P>PROBLEM TO BE SOLVED: To properly connect wiring between an angle detector and a circuit board arranged at the rear end side of a motor in an actuator in which an angle detector of a magnetic encoder is incorporated inside a wave reduction gear. <P>SOLUTION: In an actuator 1 in which an angle detector 13 of a magnetic encoder for detecting the rotational position of a motor 3 is incorporated inside a wave reduction gear 5, detection signals from Hall elements 11a, 11b of the angle detector 13 are transmitted via sensor lead wires 17 drawn out through wiring holes 36a, 33a, 35a, 37a formed inside the motor 3 to a sensor signal converter board 14 arranged on the rear end side of the motor. Since the wiring is not required to be drawn out to the exterior, indirectly routed along the exterior of the motor 3, and to be brought out to the rear side, the wiring is not mechanically damaged. Since the wiring is drawn out with the shortest possible wiring distance, the influence by electromagnetic noise is also reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT |
