Abstract
An electromagnetic linear driving device comprising a stationary magnetic member, a first winding wound around the stationary magnetic member along the longitudinal direction thereof, and a movable permanent magnet for generating a magnetic flux which links some turns of the winding. A second winding is wound around at least one terminal of the stationary magnetic member so as to generate a magnetic flux opposing the magnetic flux generated by the first winding.
