چکیده
The effectiveness of the electric braking system largely depends on how is carried out, whether characteristics that it forms are acceptable for a given vehicle, simple and reliable technical solutions embedded in are, where energy used. With braking, possible not only to extinguish electrical resistor, but also send back storage device again use traction mode. This paper analyzes most common methods used systems drives operation vehicles. As main criterion evaluating method its indicators selected. results scientific research proposed new which provides better performance implementation, considered. When implementing this method, DC motors operated by sequential excitation generators. current field windings regulated DC-DC-converter. Energy power circuit accumulated devices filled, extinguished from output DC-DC-converter own needs. In case, formed as generators independent excitation. To increase efficiency at low speeds, necessary smoothly regulate resistance resistors shunting them with transistor switches.

متن کاملAnalysis of Hoisting Electric Drive Systems in Braking Modes
Braking in hoisting drives is used to reduce the speed of the load (cargo) or to stop it completely. Braking can be realized using electrical and mechanical means; mechanical brake is used to hold the suspended cargo after disconnecting the driving motor from the supply. In modern hoisting electric drive systems, in addition to mechanical braking, electric braking is also used. Electric braking...
