SETT OCH ANORDNING FOR BESTEMNING AV ETT FLERTAL VINKELLEGEN FOR EN ROTERANDE KROPP RELATIVT ETT REFERENSVINKELLEGE

摘要

A system utilizing a single sensor for locating angular positions of a rotating member relative to an angular reference position is provided with means which, for each revolution of the rotating member, generates a bipolar reference signal at the reference position and a bipolar position signal of reversed polarity from the bipolar reference signal. At the second half waves of the bipolar reference and position signals respective unidirectional reference and position signals are generated. The latter are converted to logic signals corresponding to angular positions of the rotating member relative to the reference position and the unidirectional reference signals are utilized to control cycle repetition.
