This new axial piston motor has been developed by Linde Hydraulics to achieve maximum speeds higher than conventional swash plate designs. Additionally, a large displacement volume in a compact design means wider transmission speed ranges, normally achieved with modular transmissions, are possible. The HMV-02 D is about 30 % lighter than a motor combined with transfer gear box, and has a smaller footprint. The increased power density was achieved through the innovative design of two in-line swash plate rotating groups in a "face-to-face" arrangement. As a result, only one control is needed to adjust the displacement volume of the two motors. The inner lateral forces are compensated so that only one drive shaft and two (instead of four) bearings are required for both rotating groups.
