Description

Предметом изобретени   вл етс  устройство дл  регулировани  скорости трехфазного асинхронного двигател , две фазные обмотки которого соединены открытым треугольником , а обмотка свободной фазы обтекаетс  посто нным током. В известных асинхронных двигател х с такой же схемой включени  обмоток не обеснечиваетс  достаточно нлавна  н глубока  регулировка скорости. В предлагаемом устройстве увеличении диапазона регулироваии  скорости снижени  тока подмагиичиванн  в обмотке свободной фазы достигаетс  благодар  тому, что в лииейный ировод , идущий от сети к вершине открытого треугольника, включеи выир митель . На чертеже изображена схема такого устройства.The subject of the invention is a device for controlling the speed of a three-phase asynchronous motor, the two phase windings of which are connected by an open triangle, and the winding of the free phase is flowed by direct current. In the well-known asynchronous motors with the same winding switching circuit, there is no sufficiently well-defined and deep speed control. In the proposed device, an increase in the range of regulation of the rate of current reduction in the magnetized windings in the free phase is due to the fact that the diverter is turned on in the linear cable from the network to the top of the open triangle. The drawing shows a diagram of such a device.

В средний линейный нровод стаюра трехфазного асинхронного двигател , включенного но схеме открытого треугольника, включаетс  вынр митель /. Треть  фаза статора замыкаетс  через другой вынр мнтель 2 на сопротивление 3. Благодар  наложению на двигательныйIn the middle linear wire of a three-phase asynchronous motor, connected to an open triangle circuit, the turner is turned on /. The third phase of the stator closes through the other terminal 2 to the resistance 3. Thanks to the imposition on the motor

режим двигател  тормозного действи  обратного вращающегос  пол , вызываемого несимметрией в обмотке статора, а также торможени , создаваемого протекающим во всех трех фазах статора посто нным током, достигаетс  снижение скорости двигател  как при нагрузке , так и при холостом ходе, а также «генераторное торможение ирн скорости ниже синхронной. Измен   величину сопротивлени  3 в свободной фазе статора, а также мен   сопротивле1И е роторной цени , можно плавко измен ть скорость двигател .the mode of the braking motor of the reverse rotating floor caused by asymmetry in the stator winding, as well as the braking generated by the direct current flowing in all three phases of the stator, reduces the motor speed both under load and idling, and also "generator braking speed ip below synchronous. By changing the value of resistance 3 in the free phase of the stator, as well as changing the resistance of the rotor value, it is possible to smoothly change the speed of the engine.
