Abstract
Relay drive for a polarized relay having an armature that can be moved in at least one working air gap provided between two pole faces of a split yoke and at least one permanent magnet, as well as a coil permeated with parts of the yoke, or a core directly connected therewith, wherein at least one pole face cooperating with the armature or located thereon is formed from one pole face of the permanent magnet and another pole face cooperating with the armature or disposed thereon is formed either by a pole face of another permanent magnet or of a soft-iron part, said soft-iron part being interchangeable with a permanent magnet of the same size.
Claims14
A relay drive for a polarized relay, comprising:
- a split yoke having a plurality of limbs;
- an armature moveably disposed between said limbs of said yoke;
- coil means for inducing a magnetic field within said yoke;
- a first flux guide magnetically coupled to said yoke and comprising a permanent magnet, one pole face of said permanent magnet defining a first pole face;
- and
- a second flux guide, detachably mounted within said relay, magnetically coupled to said yoke and directly defining a second pole face;
- said first and second pole faces at least partially defining at least one air gap, said air gap permitting movement of said armature between said limbs of said yoke.
