Variable displacement motor with axial piston rotary group of bent axis design, for hydrostaticdrives in open and closed circuits. The motor is suitable for both mobile and industrial applications. The wide control range of the variable displacement motor allows it to meet the requirements of high speed and high torque. The displacement is infinitely variable in the range Vg max to Vg min = 0. Output speed is proportional to flow and inversely proportional to displacement. The output torqueincreases with the pressure drop between the high and low pressure sides and with increasing displacement. – Wide control range for hydrostatic drives – Various control and regulating devices – Cost saving through elimination of gearbox and possibility of using smaller pumps – Compact, robust bearing system with long service life – Low unit power – Good starting characteristics – Low inertia – Wideswivel range
