About ELEVATOR Braking Resistor
An elevator braking resistor (or
Dynamic Braking Resistor, DBR) is a safety component that absorbs and dissipates excess electrical energy as heat when an elevator slows down or lowers a heavy load, preventing overvoltage in Variable Frequency Drives (VFDs) and ensuring smooth, controlled stopping, protecting both the motor and drive system by converting regenerative power into heat instead of causing faults or jerky movements
