Description

Предметом насто щего изобретени   вл етс  «SMepHTevTbHoe устройство дл  системы автостабилизации скорости в электропривадах с широки М изменением скорости. Основной частью устройства  вл етс  таходинамо посто нного тока, воздействующа  на какой-либо -регул тор скорости.The subject of the present invention is a "SMepHTevTbHoe device for a speed auto-stabilization system in electric drives with a wide M speed variation. The main part of the device is a direct current tachodynamic device acting on any speed controller.

Сущнюсть иеобретени , заключающа с  в том, что в качестве таходинамО применен сериесный генератор, к обмотке возбуждени  которого нриключена цепь управлени;  регул тора, по сн етс  чертежом, на котором изображена принципиальна  электриче ека  схема предлагаемого устройства.The essence of the invention is that a serial-type generator is applied to the treadmill, with a control circuit connected to the field winding; controller, see the drawing, which shows the basic electrical circuit of the proposed device.

Таходинамо св зана общим валом или редукторам с регулируемым двигателем. Таким образом регул тор напр жени , воздейству  соответствующим образом на скорость двигател  и таходинамо, стремитс  поддерживать посто нны-м напр лсение на обмотке возбуждени  таходинамо, а следовательно, и скорость двигател .A series of special-purpose tachodiam T is connected to an adjustable potentiometer P. The voltage from the excitation winding of the tacho dynamo is supplied to the voltage regulator. The tahodinamo is connected by a common shaft or gearbox with an adjustable motor. Thus, the voltage regulator, acting accordingly on the motor speed and the tahodinamo, tends to maintain a constant voltage on the tahodinamo excitation winding, and consequently, the motor speed.

Принудительным регулированием сопротивлени  г- соответственно регулируетс  скорость Лх двигател . Таходинамо рассчитываетс  таким образом, что имеет полное поле при минимальной скорости двигател  и работает с посто нным током нагрузки .By compulsively controlling the resistance r - the speed Lx of the engine is adjusted accordingly. The tacho dynamo is calculated in such a way that it has full field at minimum engine speed and operates with a constant load current.

По мнению изобретател , предлагаема  схема имеет следующие достоинства:According to the inventor, the proposed scheme has the following advantages:

1)освобождает от необходимости примен ть специальную . стабилизацию тока возбуждени  таходинамо, благодар  чему повышаетс  точность регул тора ,1) exempts from the need to apply a special one. stabilization of the excitation current of the tachodynamo, due to which the accuracy of the controller is increased,

2)увеличивает чувствительность авторегул тора скорости, так как подводимое к нему напр жение измен етс  не только за счет скорости таходипамо , но и за счет его пол .2) increases the sensitivity of the autoregulator of speed, since the voltage applied to it changes not only due to the speed of the tahodipamo, but also due to its field.
