ABSTRACT:
An electromechanical pulse counter for counting applied current pulses includes a magnetizable disc-shaped armature mounted for rotation about a fixed axis. Magnetic stepping poles diametrically disposed adjacent the circumference of the armature are momentarily magnetized by a magentic winding upon application of each current pulse to establish diametrically opposed magnetic poles in the armature. Permanent indexing magnets diametrically disposed adjacent the circumference at an angular position relative to the stepping poles magnetically coact with the magnetic poles established in the armature following each current pulse to cause the armature to rotate to align the established magnetic poles with the poles of the indexing magnets. Each subsequent current pulse causes another pair of diametrically opposed magnetic poles to be established in the armature, and the armature to subsequently rotate to align the newly established magnetic poles with the indexing magnets. A pointer coupled to rotate with the armature indicates on an externally viewable scale from the total angular displacement of the armature the number of current pulses applied to the counter. The pointer is returned to its initial position by applying a series of current pulses of opposite polarity to the magnetic winding. Additional stepping poles may be provided on the opposite side of the indexing magnets for magnetization by an alternate source of current pulses to provide bidirectional up-down counting of applied pulses.
