Rexroth A6VM80 A6VM107 Variable Piston Motor,A6VM80 Hydraulic Motor

A6VM Variable Motor, with an axial tapered piston rotary group of bent-axis design for hydrostatic drives in open and closed circuits. For use in mobile and stationary application areas. The wide control range enables the variable motor to satisfy the requirement for high speed and high torque.

Name	A6VM Series Hydraulic Variable Axial Piston Motor
Series	Series 6X
Sizes	28,55,80,107,140,160,200,250,355,500,1000cc/rev
Nominal Pressure	400 bar
Maximum Pressure	450 bar
Operation Mode	Open and Closed Circuit

The displacement is infinitely variable. the output speed depends on the flow of the pump and the displacement of the motor. The output torque is increases with the pressure differential between the high and low pressure side and with increasing displacement.The output torque is increases with the pressure differential between the high and low pressure side and with increasing displacement
