ELECTROMAGNETIC LINEAR MOTION DEVICE

Herein disclosed is an electromagnetic linear motion device having an armature or movable core which is wrapped with a control coil cutting across a magnetic field established through a rectilinear air gap which is defined by inner and outer pole pieces having opposite polarities and positioned in parallel to and at least partly coextensive to each other. The device uses a support mechanism including bearings to longitudinally movably support the movable core and resilient suspension means which is adapted to have the movable core balanced in the longitudinal direction of the device. Such device can be used as a linear motor or a signal generator where minute and precise linear motions are required.
