Out with valves, in with electric motors: KOLLMORGEN has developed a ready-made drive solution for hydraulics applications for the S700 series´ servo drives. The new technology improves the energy efficiency of applications that need the high power density associated with hydraulics. Two other benefits are control precision and longevity.
The pressure and volume flow control for hydraulic applications is generally achieved with the help of variable displacement pumps. Standard solutions use comparatively primitive asynchronous motors for this, which drive the variable displacement pumps. A control system responsible for ensuring compliance with setpoints, is connected to this arrangement.
