ABSTRACT:
The force motor of the present invention controls the local magnetic field through a uniquely designed mechanical structure of the internal components. The mechanical structure divides the magnetic field in the force motor into three sections. The force produced on the armature by the magnetic field in the first section increases exponentially as the armature approaches the housing. The force produced on the armature by the magnetic field in the second and the third sections, as the armature approaches the housing, counter balances the rise in the force due to the magnetic field in the first section. Thus, a flat F-S curve over a long stroke length is obtained.
