Hydraulic Motor

M+S Hydraulic Motor Orbit motors convert hydraulic energy (pressure, oil flow) into mechanical energy (torque, speed).

Hydraulic orbit motors operate on the principle of an internal gear (rotor) rotating within a fixed external gear (stator). 

The internal gear transmits the torque generated by the application of pressure from hydraulic oil fed into motor which is then delivered via the motor's output shaft. 

Orbit motors have high starting torque and constant output torque at wide speed range.

 

 

 

MR Series have a spool valve: the distribution valve is integrated in the outpust shaft. The cardan shaft thus rotates the distribution valve and mechanical energy from the gerotor set to the output shaft.
