b maXX 5100 - Rectifier and regenerative feedback units

With electric drives, energy costs often account for almost 90 percent of the total life cycle costs. Regenerative systems help to reduce the total cost of ownership.

The tried-and-tested b maXX automation and drive solution from Baumüller is being expanded with the regenerative feedback units of the b maXX 5100 series. The b maXX 5100 series supplies one or more power modules and feeds braking energy back into the power supply in a sinusoidal shape.

Energy-efficient power input of braking energy

Considering energy costs, there are significant savings opportunities for the user over the service life of a machine. Regenerative feedback systems help to reduce energy consumption by feeding the braking energy back into the power supply instead of converting it into heat via a ballast resistor — which also benefits the environment.

b maXX 5100 units are seamlessly integrated into the b maXX automation and drive solution from Baumüller. By realizing 3 different sizes over a power range from 36 kW to 200 kW of DC link voltage, the user benefits of the b maXX series of modularity and flexibility have been consistently implemented. System consistency is ensured both by adopting the housing technology and connection data and by integrating the parameterization of the b maXX 5100 into the existing b maXX ProDrive operating software.
