Electro-hydrostatic actuator (EHA) is a highly integrated and self-contained direct drive
actuator system that aims at replacing the traditional hydraulic system. EHA was widely used …

Abstract Recently, the Electro-Hydrostatic Actuator (EHA) has been developed as a result of
research on energy saving. EHA is usually composed of a direct driven pump from an …

Typical hydraulic system, although it is widely applied in industry because of its high energy
density, its actual operational efficiency is only 23%–25% owing to very high energy losses …

One way to increase the compactness and power density of electro hydraulic power units is
to increase the rotational speed level. Hence, a high-speed electrical drive and a high …
