Abstract
Изобретение относитс к электротехнике и может быть использовано в подъемно-транспортных механизмах. Целью изобретени вл етс расширение диапазона регулировани . Согласно данному способу осуществл етс регулирование скорости электропривода в зоне при P const путём уменьшени тока возбуждени электродвигателей 1 и 2 поочередно в два этапа. Сначала у электродвигател 1 плавно снижают ток возбуждени до нул регул тором возбуждени 9. ТЬк возбуждени электродвигател 2 остаетс номинальным . Затем снижают ток возбу дени у электродвигател 2 от номинальной величиньг до требуемой под контролем датчика тока 6. 2 ил. i (ЛThe invention relates to electrical engineering and can be used in hoisting and transport mechanisms. The aim of the invention is to expand the range of regulation. According to this method, the speed of the electric drive is controlled in the zone at P const by reducing the excitation current of the electric motors 1 and 2 alternately in two stages. First, in motor 1, the excitation current is gradually reduced to zero by the excitation control 9. The drive excitation of the motor 2 remains nominal. Then, the excitation current of the electric motor 2 is reduced from the nominal value to that required under the control of the current sensor 6. 2 Il. i (L
