Our high-precision motors are custom-built for applications where very high runout uniformity is required, especially in the low speed range.
They have an extremely low geometrical non-uniformity of 0.28% for RMHP motors and 0.73% for AEHP motors.
Due to low rotating masses, Düsterloh hydraulic motors allow a quick change of the direction of rotation.
Displacement [cm3/rev] 43,7 - 109,5
Power [kW] up to 18
Speed range [rpm] 1 - 2000
Torque [Nm] up to 310
Axial piston motors with swash plate
Radial piston motors with polygon rings and gap seal in the control system
The superior running characteristics and extremely low mass moments of inertia of the high-precision motors are of great importance when testing the adjustment of commercial aircraft wing flaps. During the test bench runs, components are subjected to up to 50 changes in direction of rotation per second.
