To the question about the braking mode of the thyristor asynchronous electric lifting mechanisms.

Abstract

The thyristor asynchronous electric drive system with phase control with speed feedback allows you to get a brake descent of goods on the crane in the modes of opposition or dynamic braking. It is shown that for stopping loads on cranes, it is advisable to use an anti-switching mode with a corresponding resistance value in the rotor, since this will result in less engine heating, no vibrations and a simpler control circuit compared to the dynamic braking mode.
