AbstractGovernment-enforced regulations have led to increasing demands for energy efficient solutions in the industry. To diminish the losses of hydraulic systems and to increase their energy efficiency, several pump control methods have been developed. In this work, a new experimental direct drive actuator solution, powered directly by a servo motor controlled hydraulic pump-motor, is evaluated. As an additional innovative feature, a load compensating hydraulic circuit has been introduced in order to reduce power consumption even further. The study presents results of performance measurements of this new concept.
