Abstract
Изобретение относитс к электротехнике и может быть использовано дл регулировани и стабилизации скорости перемещени гибкого материала в текстильной , кабельной, полимерной и других област х промышленности. Цель изобретени - повышение надежности и быстродействи электропривода. Электропривод содержит электродвигатель, корна обмотка 1 которого подключена к источнику тока 2, а обмотка возбуждени 3 - к источнику тока 4. Импульсы с импульсного датчика скорости 8 поступают на Т-триггер 9, далее на формирователь синхроимпульсов 11 и регулируемый формирователь временных импульсов 10. Если длительность интервала времени между двум импульсами с датчика скорости больше или меньше заданной длительности импульса, формируемого регулируемым формирователем временных импульсов 10, то на выходе Т-триггера устанавливаетс сигнал, вызывающий размыкание или замыкание ключа 5 и, следовательно , необходимое увеличение или уменьшение скорости двигател . Частота автоколебаний скорости обратно пропорциональна количеству импульсов датчика скорости на один оборот. 2 ил. (Л СThe invention relates to electrical engineering and can be used to control and stabilize the speed of movement of a flexible material in the textile, cable, polymer, and other industries. The purpose of the invention is to increase the reliability and speed of the electric drive. The electric drive contains an electric motor, the root winding 1 of which is connected to the current source 2, and the excitation winding 3 to the current source 4. The pulses from the pulse speed sensor 8 are sent to the T-flip-flop 9, then to the sync pulse shaper 11 and the adjustable time pulse shaper 10. If the duration of the time interval between two pulses from the speed sensor is more or less than the specified pulse duration generated by the adjustable shaper of time pulses 10, then at the output of the T-flip-flop sets with a signal that causes the opening or closing of the switch 5 and, therefore, the necessary increase or decrease in engine speed. The frequency of self-oscillations of speed is inversely proportional to the number of pulses of the speed sensor per revolution. 2 Il. (Ls
