Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The paper deals with the possibility of application of electric drives with step and valve motors in welding equipment. Examples of performed developments of mechanized and automatic welding-surfacing equipment for various purposes are used to demonstrate the advantages of application of brushless motors as a set with computerized systems of control and regulation in different units to perform diverse technological functions. Effectiveness of application of step and valve electric drives for modulated and pulsed feed of electrode wire is particularly emphasized. Goods prospects for development of equipment with application of electric drives with step and valve electric motors are noted. 11 Ref., 8 Figures.
