Electromagnetic force-transducer

摘要: An electromagnetic force-transducer comprising a magnetic circuit and an coil kept movable in the static field provided by said circuit. The consists of two coaxial parallel windings wound on common frame with distance between both. comprises inner path outer cylindrical clearance left therebetween. In upper lower part there are gap gap, respectively. that directed oppositely to each other. is vertically clearance, positioning one other gap. current-supplied directions opposite produce their respective forces same direction. Thus, fields produced cancelled other, so resultant entire does not affect at gaps
