ABSTRACT:
A driven paramagnetic member, located between two stationary magnetic members, is moved in opposite directions by alternately energizing intermediate magnets which are located between the stationary members and the driven member. To conserve electrical energy, the ampere-turns of the intermediate magnets are reduced gradually while the members are moving together to reduce the gap thicknesses therebetween.
