Abstract
Изобретение относитс к электротехнике и может быть использовано дл регулировани однофазных коллекторных электро- двигателей. Цель изобретени - улучшение коэффициента мощности и регулировочных свойств электропривода. Электропривод содержит электродвигатель 1, подключенный к источнику 2 однофазного переменного тока через противопараллельно включенные тиристоры 4, 5. Входы блока 6 фазового управлени соединены с пусковым контактом 7 и датчиком 8 скорости. Вход генератора 12 импульсов соединен с пусковым контактом 7. В данном электроприводе за счет применени конденсатора 9 и тиристоров 10, 11 обеспечиваетс плавное включение электродвигател 1. 3 ил.The invention relates to electrical engineering and can be used to regulate single-phase collector motors. The purpose of the invention is to improve the power factor and the adjustment properties of the electric drive. The electric drive contains an electric motor 1 connected to a single-phase alternating current source 2 via anti-parallel thyristors 4, 5. The inputs of the phase control unit 6 are connected to the starting contact 7 and the speed sensor 8. The input of the pulse generator 12 is connected to the starting contact 7. In this electric drive, due to the use of a capacitor 9 and thyristors 10, 11, the electric motor 1 is switched on smoothly. 3 sludge.
