Advantages of using chokes : 1) provides smooth starting and braking of the electric motor without impacts in the mechanism, which increases the service life of the motor and the entire mechanism as a whole; 2) allows you to limit the amount of starting current and starting torque; 3) provides smooth or step speed regulation from 10% to 100% of the nominal; 4) compact, easy to configure, operate and maintain; 5) saves you money by reducing the energy consumption of the mechanism and increasing the service life of its elements. Throttle variable electric drive components Crane chokes ДДП Thyristor speed controllers DRS Chokes are mainly used in electric drives of crane mechanisms, both for the movement of bridges and bogies, and for lifting mechanisms. are intended for smooth or step regulation of the speed of production mechanisms equipped with asynchronous electric motors with a wound rotor and chokes to limit currents in starting and braking modes.
