High precision motors
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.
Performance features
- Lowest speeds (uncontrolled 1 min-1, controlled 0.1 min-1)
- Highest speed constancy (standard deviation 0.011 min-1 at 1 min-1)
- Extremely low mass moment of inertia
- Full torque over the entire speed range
- Excellent suitability for closed-loop control applications

Test stands for wing flaps
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.
