Description

На/сто щее предложение касаетс  схемы включени  электри1еского привода дл  врубовбй машины, состо щего из двух питаемых от одной сети асинхрбнных двигателей Один из этих двигателей служит дл  сообщени  .машине поступательного перемещени  (двигатель подачи), а другой дл  привода рабочего органа (главный двигатель).The current proposal concerns the connection circuit of an electric drive for a cutting machine consisting of two asynchronous motors powered from one network. One of these engines serves to communicate the forward movement machine (feed motor) and the other to drive the working element (main engine) .

Изобретение имеет целью осуществить автоматическое регулировайие скорости двигател  подачи в некоторь х пределах в зависимости от нагрузки главного двигател .The invention aims to realize an automatic adjustment of the feed speed of the engine, in part, depending on the load of the main engine.

Предлагаетс  включить последовательно с обмоткой статора двигател  подачИ вторичную обмотку сериесного трансформатора , первична  обмотка которого включена в цепь статора главного двигател . Благодар  этому напр жение на зажимах двигател  подйчи будет равно разности напр жени  сети и напр жени  вторичной обмотки сериесного трансформатора ,г It is proposed to connect in series with the stator winding of the feed motor and the secondary winding of a series-type transformer, the primary winding of which is connected to the stator circuit of the main motor. Due to this, the voltage at the terminals of the motor will be equal to the difference of the network voltage and the voltage of the secondary winding of the series transformer, g

In order for the engine to respond significantly to the voltage change on its distance in the sense of changing its number of rotors, the rotor can be made ii in the form of a massive iron cylinder without a winding or with a squirrel winding of great resistance. Engine n cottages and g; The engine can be connected to one machine, as shown in FIG. 2 and 3.
