摘 要：
PURPOSE:To stably control a moving unit, by losing the weight of the moving unit moving in the vertical or slanting
direction, with the tensile force of a spring plate. CONSTITUTION:A stator frame is fitted on a motor fixed way, and a mover frame is butted to the open end section. A guide rod is penetrated into the sleeve bearing of the mover frame, and the mover frame interior is provided with a mover. Then, by conducting stator windings electrically, the mover is
vertically and linearly moved in parallel with a stator. Then, at the lower end of the mover, a constant-tension spring unit 9 for losing the weight of the mover is fitted. The unit 9 is composed of a bobbin 13 supported rotatably by a unit frame 10 fixed on the lower end face of the mover, a spring plate 14 lap-wound on the
bobbin, and position detecting means 18, 19 for detecting the elongation (return) of the spring plate. Then, the return force of the pulled- out spring plate 14 is equal to the gravity with addition of the weight of
