<p>DrivAx IPS Variable speed drives</p>

Motor pump combination

Servo drives consist of a servo motor and a variable-speed pump. Thus, they combine the advantages of hydraulics with the benefits of servo drives: High power densities, low inertias and robust drive elements meet dynamic and precise speed control. The result: energy consumption is reduced by up to 80%. Also heat and noise emissions as well as the complexity of the system are reduced compared to classic hydraulic drives.

DrivAx IPS

DrivAx IPS is a hydraulic variable speed drive suitable for all applications with high power density and high dynamics

Consisting of a servomotor and an internal gear pump, the DrivAx IPS variable speed pump drive combines energy efficiency with high power density and robustness of hydraulics.

Unlike to conventional, valve-controlled hydraulic systems, the DrivAx IPS offers performance on demand. This means: the volume flow and pressure are regulated by the electric motor and the internal gear pump. In the partial load range and outside the machine cycle, the system can work at reduced speeds or stop. DrivAx IPS not only reduces noise by up to 20 dB(A), but also energy consumption by up to 80%, while minimizing the CO2-emissions. In addition, the lower average pump speed lowers the oil temperature in the system and minimizes the cost and energy required to cool the hydraulic system. Operators benefit from total operating costs (TCO) reduced by up to 35%. Hydraulic power units and complex piping can be omitted or reduced to a minimum.

DrivAx IPS offers simple integration and allows the construction of compact, low-noise machines with higher functionality and productivity at the same time.

DrivAx RQ4

DrivAx RQ4 is a hydraulic variable speed drive suitable for all applications with high power density and high dynamics

Consisting of a servomotor and a directly mounted radial piston pump, the DrivAx RQ4 variable speed pump drive combines energy efficiency with high power density and robustness of hydraulics.

Unlike conventional, valve controlled hydraulic systems the DrivAx RQ4 offers power on demand. This means: flow and pressure are controlled via the electric motor and the radial piston pump. In the part load range and outside the machine cycle, the system can thereby operate at lower speeds or stop operation at all. Thus, DrivAx RQ4 variable speed pump drives reduce not only noise by up to 20 dB(A), but also energy consumption by up to 70% while minimizing the CO2-emissions. In addition, the lower average pump speed lowers the oil temperature of the system, minimizing the cost and energy required to cool the hydraulic system. While operators benefit from reduced total cost of ownership (TCO) by up to 35%, hydraulic power units and complex piping are a thing of the past for machine builders.

The compact design of DrivAx RQ4 offers easy integration and along with reduced cooling and elimination of most noise containment components, it helps machine builders to maintaining a small machine footprint, while increasing functionality.
