Michael Gandrud, Senior Engineer, Advanced Systems Engineering, Sauer-Danfoss:
"Advancing Hydraulic Technology into the Age of Hybrid Vehicles and AC Drives"
Mechanical engineers know that many electrically powered machines use hydraulic systems for performing useful work functions. Battery powered forklift trucks, steering systems on electric vehicles, and many industrial process machines like injection molding machines are a few examples of such machines. Producers of machines that use hydraulic systems traditionally build hydraulic power packs from modular motors, pumps, inverter drives, valves, and interconnecting components from separate vendors.
We are here to introduce technical advantages and design considerations of the "Integrated Hydraulic Package" (IHP) concept. An IHP is an integrated unit that incorporates a motor drive inverter, an electric motor, a hydraulic piston pump, and integrated valve functionality. The IHP is a compact and efficient integrated unit that turns AC or DC power into precisely controlled hydraulic power. Sauer-Danfoss has been awarded three US patents in these technologies with over twenty US and global patents pending.
