FIELD: physics; measurement. ^ SUBSTANCE: invention is related to the field of instrument-making and may be used for control of induction motor rotation, in particular, gyroscope hydraulic motor. In order to obtain this result, device incorporates supply bus 1, static current converter 2, switchboard 3, control and alarm unit 4, differential amplifier 5, comparator 6, Schmitt trigger 7, reference voltage source 8, current detector 9. Current detector 9 defines current value in circuit, comparator 6 compares it to permissible limit value, and current exceeds this value, load is disconnected, which prevents short circuit. ^ EFFECT: higher reliability. ^ 1 dwg |
