Abstract

PURPOSE: To reduce an insensitive region without a flexible lead by using a contactless linear motor and using a differential inductor-type displacement detector for position detection.
CONSTITUTION: Input voltage EX is compared with feedback voltage Vf, which is obtained by position mechanism PF, in differential amplifier A, and amplifier A outputs a DC voltage corresponding to deviation, and the DC voltage is applied to coil 13 of linear motor LM to flow current Im. Then, movable magnet 14 is moved in the left direction in the gap between cores 11 and 12 according to the magnitude of Im. When the relation between EX and Vf in magnitude is reverse, the direction of Im is reverse, and movable magnet 14 is moved in the right direction shown in the figure. Short-circuit ring 22 of position detector PD is displaced by movement of magnet 14. Coils 25 and 26 which constitutes PD are connected in series, and output Er of exciting power source 24 is applied to them.
