Abstract

FIELD: variable-speed precision electric drives. SUBSTANCE: valve-type drive has current setting element 1, intermittent-duty switch 2, series-connected amplifier 3, valve-type converter 4, and motor 5 connected to load 6 and to emf sensor 7, as well as functional converters 8,9. Control angle varies as function of desired current which linearizes static characteristics of valve-type converter in actual emf. EFFECT: improved operating reliability. 1 dwg

Использование: широкорегулируемые и прецизионные электроприводы. Цель изобретения - упрощение и повышение надежности электропривода. Вентильный электропривод содержит задатчик тока 1, ключ прерывистого режима 2, последовательно соединенные усилитель 3, вентильный преобразователь 4 и двигатель 5, соединенный с нагрузкой 6 и датчиком ЭДС 7, а также функциональные преобразователи 8,9. Благодаря изменению угла управления в функции заданного тока в фактической ЭДС выполняется линеаризация статических характеристик вентильного преобразователя.Usage: wide-adjustable and precision electric drives. The purpose of the invention is to simplify and improve the reliability of the electric drive. The valve actuator contains a current controller 1, an intermittent mode switch 2, a serially connected amplifier 3, a valve converter 4 and a motor 5 connected to a load 6 and an EMF sensor 7, as well as functional converters 8.9. By changing the control angle as a function of the set current, the linearization of the static characteristics of the valve converter is performed in the actual EMF.
