Direct driven hydraulic systems have improved energy efficiency and controllability compared to traditional valve controlled hydraulic systems. Direct driven hydraulic systems control the pump’s rotational speed and direction to control the flow, rather than restricting flow with valves like in traditional systems. This eliminates the throttling losses of the valves. Additionally the motor and pump can be closer to the actuator, which enables additional energy saving by minimizing friction loss of the fluid. This study presents the development of a direct driven hydraulic test setup. It is equipped with additional sensors to enable the measurement of the system’s efficiency. The study includes the description of the system’s components, the measurement methods and the design of the system.
