Many types of drives can fulfil the elementary function of driving a machine but . . .

Düsterloh hydraulic motors have lots of additional features and characteristics which other types of drives cannot match. This is why Düsterloh hydraulic motors are the first choice for solving a wide variety of complex drive problems.

Düsterloh hydraulic motors have a high starting torque. This is required for instance, for safe operation of the heavy gates on the material lock in a nuclear power plant or to hand over the weighty coils in a rolling mill.

Due to the low amount of revolving mass, the rotational direction can be quickly changed in Düsterloh hydraulic motors. This feature is very important in many test benches; when performing vibration tests on motorcycle forks or when testing the adjustment of wing flaps on aircrafts. The components can perform up to 50 rotational direction changes per second.

An exact adherance to the specified rotational speed profile is of essential importance for many fields of application of hydraulic motors. Düsterloh now presents a new generation of motors, for which a significantly improved constancy of rotational speed was achieved compared to conventional motors.

Design modifications in the flow control inside the motor as well as in the

arrangement of the pistons have led to significant improvement of the constancy

of the rotational speed. In addition, the speed range was clearly extended

downwards. For the standard motor which is already precise in competitive -1comparison, the ability to run is ensured for a minimum speed of 5 min .

The high precision motor can achieve speeds of -1significantly less than 1min with already good

constancy of speed in unregulated operation. The -1maximum speed is still up to 2000 min ,

depending on the motor size.

RM series »

Radial piston motorsType RM80N - RM5000X



The radial piston hydraulic motor has been designed with a high load capacity.

It is efficient, has a low moment of inertia and is capable of very low speeds and has excellent reversing properties.

The concept features make it extremely quiet, being suitable for servo control systems with facility to work either as a motor or pump in both directions.

Drive Motor: consists of a close grain, high strength, cast iron cylinder block. Eccentric crankshaft concept.

Operating characteristics: five radial piston/connecting rod assemblies bear on the crankshaft which is located by heavy duty tapered roller bearings.

Crankshaft bearings: preloaded to take the thrust in both axial directions, ensuring silent running and allows heavy radial and axial loading on the output shaft (e.g.

gear drives).

Connecting rod: the computer optimated design is hydrostatically balanced on the crankshaft with sufficient leakage to ensure lubrication and cooling. Friction losses are

reduced to a minimum and stick slip action is avoided at low speeds. High starting torque and running torque combined with high speeds are important features of the

design. Long service life is assured since con-rod slippers are uneffected by contamination and self-adjustable. Non-flammable fluids have been used with success. Noise

generation is also reduced by the cushioning effect of the hydrostatic bearing design.
