摘要: An electronic control device for controlling the velocity of a machine element to be operated at desired velocity, in which pick-up forms an a.c. voltage with frequency proportional element; electrical signal is obtained from this actuates member influencing sense cancellation deviation velocity; circuit includes pulse former connected rectangular pulses equal length and height output applied stage d.c. representing compared reproducing actual produced value; voltage, turn, by means controlled accordance stage.
