1. A reciprocating electrical machine comprising:
- a magnetically actuatable reciprocatable armature and means supporting it for movement;
permanent magnet means associated with the armature and supporting means;
electrical winding means disposed to produce a magnetic field for reciprocating the armature in association with the field of the permanent magnet;
driving means comprising a source of electrical pulses;
means for applying pulses alternately to each of said winding means to cause said armature to be reciprocated;
switch means controlling power to each of said windings;
an additional pair of windings in coupling relationship with said first windings;
first and second flip-flop means connected to control the switch means associated with said first windings;
said additional pair of windings being connected to said first and second flip-flop means; and
said source of electrical pulses being connected to said first and second flip-flop means.

Abstract
A completely sealed magnetically driven pump having a piston armature driven by electrical windings. Unique electrical driving circuits are provided for the pump embodying feedback windings magnetically coupled with the driving windings of the pump for controlling the reciprocation. The drive circuits are such as to facilitate driving rates, embodying particularly solid state bistable flip-flop components adaptable to be embodied in or associated with computers or other low power logic devices.
