Pulse generator

摘要

An electromechanical pulse generator includes a toothed disk driven by a rotating shaft to operate two pairs of contacts to generate one pulse output and one direction-of-rotation output. The pulse contacts and the direction-of-rotation contacts operate independently of each other. The toothed disk is rotatable and axially displaceable. The axial displacement is dependent on the direction of rotation via an inclined plane in the form of a screw thread which is rotatable by the rotary shaft. By axial displacement of the toothed disk, the direction of rotation of the shaft is detected, and by rotation of the toothed disk, the pulses are generated.
