<P>PROBLEM TO BE SOLVED: To provide an AC servomotor of good assembly workability where good heat insulation and drip proofness is provided between an anti-load side bracket and a detector cover for high reliability. <P>SOLUTION: In an AC servo-motor, a detector is mounted on an anti-load side end 3 of a shaft, and a detector cover 2 is fitted to an anti-load side bracket 1. Protruding parts 8a and 8b are provided on the diagonal line with the shaft as axial center at the opposed end faces of the anti-load side bracket 1 and the detector cover 2. A hole 9 is provided to the points corresponding to the position of protruding parts 8a and 8b. A rubber packing 7 which is compressed to a thickness equal to the total of the lengths of the protruding parts 8a and 8b of the anti-load side bracket 1 and the detector cover 2 when tightened is interposed between the anti-load side bracket 1 and the detector cover 2. <P>COPYRIGHT: (C)2004,JPO |
