b maXX 4100

Rectifier and regenerative feedback unit b maXX 4100

It is often the case with electrical drives that energy costs make up almost 90% of the overall life-cycle costs. With this in mind, regenerative systems help to reduce the total cost of ownership.

b maXX 1000 - Einspeiseeinheit und Rückspeiseeinheit

Baumüller’s tried-and-tested b maXX automation and drive solution is being expanded with the addition of the new b maXX 4100 series rectifier and regenerative feedback units. These units supplement the b maXX 4400 series, supplying one or more power modules and performing sinusoidal brake energy feedback into the system.

As far as energy costs are concerned, this offers the user the opportunity to make considerable savings over the machine’s service life. Regenerative systems also help to lower energy consumption (and do their bit for the environment) by feeding the available brake energy back into the system, rather than converting it into heat via a regenerative resistor.

The b maXX 4100 units are fully integrated into Baumüller’s b maXX automation and drive solution. The benefits which the b maXX series offers to its users, i.e., modularity and flexibility, are also provided by the b maXX 4100, thanks to the availability of three different frame sizes covering a DC link power range of 35 kW to 150 kW, the opportunity to select from various cooling methods, such as air or water cooling, and the fact that the b maXX 4100 can be integrated in the Baumüller automation environment by means of various optional fieldbuses. System continuity is ensured by using existing housing technology and connection data, as well as by parameterizing the b maXX 4100 by means of the ProDrive b maXX operating software that is already used.
