Description
НИИ электродвигател элемент 2 не шунтирует обмотку 1, то фазное напр жение сети полностью прикладываетс к этой обмотке, поскольку напр жение иа конденсаторе 3 в момент включени равно нулю. При этом нроисходит ускоренное срабатывание электромагнита из-за форсировки его возбуждени .The scientific research institute of the electric motor element 2 does not shunt the winding 1, the phase voltage of the network is fully applied to this winding, since the voltage of the capacitor 3 at the time of switching on is zero. In this case, an accelerated operation of the electromagnet occurs due to forcing its excitation.
Когда в момент включени электродвигател элемент 2 шунтирует обмотку 1 электромагнита , конденсатор 3 зар жаетс через элемент 2 до начала следующего нолупериода . В момент смены пол рности полуволны питаюш;его напр жени к обмотке 1 прикладываетс напр жение сети и конденсатора 3, который в этот момент разр жаетс . При этом скорость нарастани тока в обмотке 1 еще более увеличиваетс , компенсиру задержку при включении.When the element 2 shunts the winding 1 of the electromagnet at the moment of switching on the electric motor, the capacitor 3 is charged through the element 2 until the beginning of the next half period. At the time of the change of the polarity of the half-wave, the supply voltage is applied; its voltage is applied to the winding 1 by the voltage of the network and the capacitor 3, which is discharged at this moment. In this case, the rate of increase of the current in the winding 1 is further increased, compensating for the delay in switching on.
Применение блока форсировки позвол ет получить врем срабатывани электромагнита 0,01-0,04 с.The use of a force unit allows to obtain the response time of the electromagnet 0.01-0.04 s.
В установившемс режиме конденсатор 3 работает как реактивное сопротивление, ограничива напр жение и мощность обмотки 1 электромагнита.In the steady state mode, the capacitor 3 acts as a reactance, limiting the voltage and power of the winding 1 of the electromagnet.
Использование изобретени позвол ет упростить схему блока форсировки, повысить надежность и уменьшить стоимость электродвигател в целом.The use of the invention allows to simplify the circuit of the forcing unit, increase reliability and reduce the cost of the electric motor as a whole.
