(54) УСТРОЙСТВО ДЛЯ ПИТАНИЯ ЭЛЕКТРОДВИГАТЕЛЯ ЛЕНТОПРОТЯЖНОГО МЕХАНИЗМА(54) DEVICE FOR POWER SUPPLY OF ELECTRIC MOTOR OF BELT-STRIP MECHANISM
ВХОДОМ электронного ключа 5, второй вход которого соединен с электродвигателем 3, а выход - через фильтр б нижних частот и пррого вые элементы 7 и 8 - к выходным сигнёшьным шинам останова и обрыва 10.The INPUT of the electronic key 5, the second input of which is connected to the electric motor 3, and the output through a low-pass filter and the forward elements 7 and 8 to the output signal buses of the stop and break 10.
ВтЬрой вход электронного ключа 1 подключен к шине 11 источника питани .The second input of the electronic key 1 is connected to the power supply bus 11.
Устройство работает следующим образом.The device works as follows.
Импульсами генератора 2 (фиг.2а) открываетс электронный ключ {фиг.1 и напр жение питани по шине 11 поступает на электродвигатель 3. В паузах между импульсами генератора 2 противо-ЭДС на электродвигателе 3 (фиг.26) соответствует угловой скорости вращени . Это напр жение противо-ЭДС электродвигател 3 проходит через открытый электронный ключ 5(фиг.2в)и поступает на фильтр б нижних частот, который выдел ет посто нное значение входного сигнала. При обрыве ленты в лентопрот жном механизме напр жение на выходе фильтра б нижних частот достигает величины, при которой срабатывает пороговый элемент 8, выдакхций на выходную шину 10 сигнал обрыва. При останове ленты напр жение на выходе фильтра 6 нижних частот приближаетс к нулю, и срабатывает пороговый элемент 7, который выдает на выходную шину 9 устройства сигнал останова.The generator 2 pulses (Fig. 2a) opens the electronic key {Fig. 1 and the supply voltage across the bus 11 is supplied to the electric motor 3. In the pauses between the pulses of the generator 2, the back-EMF on the electric motor 3 (Fig. 26) corresponds to the angular speed of rotation. This counter-emf voltage of the electric motor 3 passes through the open electronic key 5 (Fig. 2b) and goes to the low-pass filter b, which extracts a constant value of the input signal. When a tape breaks in a tape-testing mechanism, the voltage at the output of the low-pass filter b reaches the value at which the threshold element 8 is triggered, pulling the output signal 10 to the output bus 10. When the tape is stopped, the voltage at the output of the low-pass filter 6 approaches zero, and the threshold element 7 is triggered, which gives a stop signal to the device output bus 9.
