Изобретение относитс к электро технике, в частности к устройствам управлени машинами переменного тока и может быть использовано в регулируемом электроприводе.The invention relates to electrical engineering, in particular, to control devices for alternating current machines and can be used in a controlled electric drive.
Известно устройство дл частотнотокового управлени машиной переменного тока, содержащее W фазный источник гармонических сигналов, подключенный ко входам hi регулируемых источников двупол рного тока, к выходам которых подключена УМ-фазна корна обмотка машины ГОВ каждой фазе обмотки формируетс ток, мгновенное значение которого пропорционально мгновенному значению выходного напр жени соответствующей фазы источника гармонических сигналов .A device for frequency-current control of an AC machine is known, containing a W phase source of harmonic signals connected to the hi inputs of adjustable two-pole current sources, to the outputs of which a UG-phase root winding of the GOV machine is formed, each instant of which is proportional to the instantaneous value of the output voltage corresponding to the phase of the source of harmonic signals.
К недостаткам устройства следует отнести-его сложность вследствие использовани регулируемых источников двупол рного тока.The disadvantages of the device include its complexity due to the use of regulated sources of bipolar current.
Наиболее близким к предлагаемому по технической сущности вл етс электропривод с частотно-токовым управлением , содержащий электродвигатель переменного тока, обмотки которого выполнены в виде двух полуобмоток на каждую фазу, соединенных общими точками через измерительные резисторы с общей точкой источника питани , многофазный источник гармонических сигналов, регулируемые источники однопол рных токов, каждый из которых выполнен на последовательно соединенных сумматоре, второй вход которого соединен с измерительным резистором, и нереверсивном управл емом выпр мителе 2.The closest to the proposed technical entity is a frequency-controlled electric drive containing an AC motor, the windings of which are made in the form of two semi-windings for each phase, connected by common points through measuring resistors with a common point of the power source, a multi-phase source of harmonic signals, adjustable sources of unipolar currents, each of which is made on a series-connected adder, the second input of which is connected to a measuring resistor And Irreversible handled by the rectifier 2.
