The SEW Eurodrive BW147 is a braking resistor designed for use with variable frequency drives (VFDs) and servo drives. This component dissipates excess energy generated during regenerative braking operations, preventing overvoltage conditions within the drive system. It is commonly integrated into motor control panels for applications requiring precise speed control and frequent deceleration.

Technical details

Applications & compatibility

This SEW Eurodrive braking resistor is essential for applications where drives frequently decelerate or stop loads, such as in material handling systems, packaging machinery, and automated assembly lines. It ensures stable drive operation by managing the energy feedback from the motor, thereby protecting the drive's internal components and maintaining system integrity.
