Description

Предметом изобретени   вл етс  устройство дл  регулировани  скорости асинхронного двигател  с фазовым ротором с использованием в качестве регулируемых сопротивлений роторной цепи управл емых ионных вентилей.The subject of the invention is a device for controlling the speed of an induction motor with a phase rotor, using controlled ion valves as adjustable rotor resistance.

Известные устройства того же назначени , у которых первична  оомотка сеточного трансформатора ионных вентилей присоединена к кольцам ротора и сеточное смеП1ение контролируетс  тахогенератором , сид щим на валу двигател , имеют малую устойчивость и небольпюй диапазон регулировани .The known devices of the same designation, in which the primary wiring of the grid transformer of ionic valves is connected to the rotor rings and the grid displacement is controlled by a tachogenerator sitting on the motor shaft, has low stability and a small range of regulation.

В предложенном устройстве эти недостатки устранены введением в цепь ротора (последовательно с управл емыми вентил ми) омических сопротивлении.In the proposed device, these disadvantages are eliminated by introducing ohmic resistance into the rotor circuit (in series with controllable valves).

На чертеже приведена электрическа  схема описываемого устройства .The drawing shows the electrical circuit of the device described.

Согласно изобретению, бесколлекторный ионный реверсивный электропривод состоит из следую цих основных частей:According to the invention, the brushless ion reversible electric drive consists of the following main parts:

а)асинхронного двигател  D с фазным ротором, снабженного стандартным магнитным реверсивным пускателем a) an asynchronous motor D with a phase rotor equipped with a standard magnetic reversing starter

б)ионного устройства дл  регулировани  скорости двигател , состо щего из шести одноанодных ионных приборов с сетками, соединенных попарно параллельно (анод одного с катодом другого) в треугольник, включенный на. кольца ротора сопротивлени  Ria-RH или непосредственно;.b) an ionic device for controlling the speed of the motor, consisting of six single-mode ionic devices with grids connected in pairs in parallel (the anode of one with the cathode of the other) in a triangle connected on. Ria-RH resistance rings or directly ;.

в)электронного устройства или: устройства с магнитными усилител ми и селеновыми выпр мител ми дл  автоматического управлени .c) an electronic device or: devices with magnetic amplifiers and selenium rectifiers for automatic control.

Регулирование скорое ги электродвигател  осуществл етс  следующим образом.The speed control of the electric motor is controlled as follows.
