Description

Известны устройства, автоматически регулирующие скорость асинхронного электродвигател  с фазовым ротором с помощью автоматического изменени  активного соиротивлени , включенного в цепь ротора. При этом напр жение датчика фактической скорости {тaxo ieтpичecкиii генератор, установле} ный на валу регзлирземого асинхронного электродвигател ) включаетс  встречно с вспомогательным напр жеЕщем.Devices are known that automatically regulate the speed of an asynchronous motor with a phase rotor by automatically changing the active coupling included in the rotor circuit. At the same time, the voltage of the actual speed sensor {max. Generator, mounted on the shaft of a regrinding asynchronous electric motor) is switched in opposite to the auxiliary voltage.

Отличительной особенностыо ощгсываемого устройства  вл етс  согласное включение всиомогательного напр жени  и напр жени  тахогенератора , что позвол ет легко осуществл ть регулирование скорости асинхронного двигател  в обе стороны от заданной величины.A distinctive feature of this device is the consistent inclusion of auxiliary voltage and tachogenerator voltage, which makes it easy to regulate the speed of an asynchronous motor to both sides of a given value.

На чертеже дана схема устройства дл  автоматического регулировани  скорости асинхронного двигател . На валу электродвигател  1 установлен тахогенератор 2, включенньи в цепь катушек электромагнитов., измен ющих сопротивление угольного регул тора 4. Дл  изменени  скорости асинхронного двигател  катушки электромагнитов 3 питаютс  посто нным током через регулировочный потенциометр 5, включенный последовательно и согласно с иапр жением тахогенератора. При увеличении скорости асинхронного двигател  возрастает ток в катущках электромагнитов 5, которые воздействуют на угольный регул тор 4, в результате чего увеличиваетс  сопротивление в цепи ротора асинхронного электродвигател  и скорость снижаетс . При уменьшении скорости асинхронного двигател  ток в катущках электромагнитов 3 уменьшаетс  и одновременно снижаетс  сопротивление в цепи ротора электродвигател .In the drawing, a diagram of a device for automatically controlling the speed of an induction motor is given. A tachogenerator 2 is mounted on the shaft of the electric motor 1, connected to the circuit of the coils of electromagnets that change the resistance of the carbon regulator 4. To change the speed of the induction motor, the coils of electromagnets 3 are fed with a direct current through an adjusting potentiometer 5 connected in series with the tachogenerator. As the speed of the induction motor increases, the current in the coils of electromagnets 5, which act on the carbon regulator 4, increases, as a result of which the resistance in the rotor circuit of the induction motor increases and the speed decreases. When the speed of the induction motor decreases, the current in the coils of electromagnets 3 decreases and at the same time the resistance in the rotor circuit of the electric motor decreases.
