Low speed measurements    

In order to learn more about the prospects of the Floating Cup Technology for hydraulic motors, measurements were performed on the Floating Cup Pump running as a motor at very low speed (0.1 rpm). The results were compared with a conventional bent-axis pump with the same displacement volume (28.2 cc) also running as a motor.
The three diagrams present the torque losses, the hydromechanical efficiency and the flow pulsations of the Floating cup machine.
The torque losses and torque variations during a revolution are extremely low and almost independent from the input pressure. The low leakage and minimal torque losses result in a high overall efficiency and excellent motor behaviour.
