ABSTRACT:
A magnetic motor for use as an actuator for devices such as relays, indicators and the like.
It comprises an electromagnetic winding having a core member to the opposite ends of which are fastened pole pieces which cooperate with a magnetically movable armature. An additional pole piece as well as a permanent magnet are also provided.
One end of the armature is caused to contact or engage one of the pole pieces or, in the alternative, to engage or contact alternatively several different pole pieces. The opposite end of such armature is shaped so as to provide a generally U-shaped air gap with the other pole piece, and the armature is so positioned as to move from one side of coplanar relationship with such other pole piece to the other side thereof.
