KEB COMBIVERT R6 -NCM - Philosophy

The kinetic energy of electric drives represents unused energy potential which - from a historical point of view - was „destroyed“ by friction loss or mechanical/electrical braking devices.Dynamic and e� ciency-optimised AC drives and servo systems with increased e� ciency create high productivity and lead to higher regenerative loads.

In combination with a regenerative unit the same frequency inverter and servo drive o� er the possibility of converting the energy, stored in the DC circuit, back into the main line power supply.

Now the system produces useful output power in the mains instead of „waste heat“ for the nearby environment.

The KEB COMBIVERT R6-NCM regenerative units are designed to supply and regenerate energy of one or more parallel drive controllers, and can be cascaded in any manner depending on the drive or regenerative capacity.

Saving energy through regeneration -

an environmental contribution that pays o� !
