Abstract: Whenever decision makers want to follow the trend towards "all-electric" machines, but still need to maintain the major advantages of hydraulic drives, electro hydrostatic actuators (EHA) have become the technology of choice for industrial applications.In an EHA, a variable speed electric motor drives a displacement pump which is directly coupled to the actuator, namely a cylinder.After proofing the functionality of this concept in many commercial applications, current developments are targeting features and levels of efficiency that will even outperform the electro mechanical state of the art.Adaptive electro hydrostatic actuators will finally be the benchmark in terms of compactness, ease of use and energy efficiency for many application classes.This paper presents two different implementations for variable pitch EHAs and a mobile device for EHA fluid management and service.
