Description

Известны устройства дл  демпфировани  подвижного элемента электромагнитных механизмов. Основной недостаток их состоит в том, что при достаточном демпфировании увеличиваетс  врем  срабатывани  подвижной части механизма, а при уменьшении времени срабатывани  возникает  вление резонанса на частоте собственных колебанийОписываемое устройство отличаетс  от известных тем, что дл  избирательного демпфировани  свободных колебаний в нем применены индикатор перемещений  кор , соединенный через усилитель с регул тором тока в цепи обмотки  кор , и лини  задержки, включенна  между источником входного сигнала, подаваемого на электромагнитный механизм, и усилителем. Регул тор тока выполнен в виде управл ющей электронной лампы, а лини  задержки служит дл  запирани  усилител  в момент срабатывани  или отпускани  подвижного элемента .Devices for damping a movable element of electromagnetic mechanisms are known. Their main disadvantage is that with sufficient damping, the response time of the moving part of the mechanism increases, and when the response time decreases, a phenomenon of resonance occurs at the natural frequency. through an amplifier with a current regulator in the circuit of the winding core, and a delay line is connected between the input source supplied to the electric ktromagnitny mechanism and an amplifier. The current controller is made in the form of a control electron tube, and the delay line serves to lock the amplifier at the moment when the moving element triggers or releases.

При использовании описываемого устройства, например, в рекордерах фототелеграфных аппаратов с чернильной записью можно увеличить скорость записи при сохраеиии хорощего качества.When using the described device, for example, in recorders of photo-telegraphic devices with ink recording, you can increase the recording speed while maintaining good quality.

Принципиальна  схема устройства дл  демпфировани   кор  рекордера фототелеграфного аппарата приведена на чертеже.A schematic diagram of a device for damping the core of a photo-telegraph recorder is shown in the drawing.

Магнитна  система рекордера содержит посто нный магнит /. полюсные надставки 2 и  корь 3. Обмотка 4 рекордера служит дл  создани  рабочего магнитного потока, привод щего в движение  корь рекордера- Последовательно с обмоткой 4 включены лампы 5 и 6. Входной ситнал с зажимов 7 управл ет усилением лампы 5, а следовательно , и величиной тока, протекаюш,его по обмотке 4. Лампа 6 предназначена дл  демпфировани  свободных колебаний  кор  3. Управл ющее напр жение на сетку лампы 6 подают через усилитель 8 с обмотки .9The magnetic system of the recorder contains a permanent magnet /. pole extensions 2 and measles 3. The recorder's winding 4 serves to create a working magnetic flux that drives the recorder's measles. In series with winding 4, lamps 5 and 6 are turned on. the current flowing through the winding 4. The lamp 6 is designed to damp free oscillations of the core 3. The control voltage to the grid of the lamp 6 is fed through the amplifier 8 from the winding .9
