POSITION SENSING APPARATUS OF AC SERVO MOTOR MAGNETIC POLE

摘要

In this paper, it is possible to reduce the number of assembly work as well as to obtain a stable detection signal by making the magnetic pole position detecting device firmly and easily mounted on the AC servo motor.;To this end, the subject matter is the substrate seating portion 4 and the substrate guide portion 7 formed integrally with the frame 2 and the substrate seating portion 4 to be in close contact with the substrate guide portion 7 to prevent left and right movements. Is a magnetic pole position detecting device for an AC servomotor comprising a printed circuit board 6 fixed to a rotation preventing jaw (8) and a hall element (5) mounted on the printed circuit board (6).
