Orbit Motors

LOW SPEED HIGH TORQUE HYDRAULIC MOTORS
OMP

Capacities 25cc - 400cc/rev


Speeds 0-1500rpm


Pressures up to 225bar
Sauer-Danfoss 'Orbit' type hydraulic motors operate on the principle of an internal gear rotating within a fixed external gear. The internal gear transmits the torque generated by the application of pressure from the hydraulic oil fed into the motor which is then delivered via the motor's output shaft. Typical applications for these motors are winch drives, mixer drives, elevator drives, small vehicle transmissions & machine tools.
 

 

 

ADVANTAGES

CONSTANT OPERATING TORQUE

Choosing the correct capacity of motor for your particular application will ensure an almost constant output torque across the operating speed range.

HIGH STARTING TORQUE

Torques from a stalled condition can be typically 80% of the equivalent running torque, ensuring good starting performance.

TWO BOLT SAE 'A' FLANGE MOUNTING
The standard mounting is the widely used SAE A two hole flange, but units are also available with the USA type 4 hole tapped flange.

HIGH PRESSURE SHAFT SEALS

High pressure shaft seals can allow units to be operated upstream of another function, without the need for additional seal drains.

Temperature

Oil temperature should be between +30ºC & +60ºC during normal operation. Oil life is greatly reduced if temperature exceeds 60ºC. As a general rule, oil life is halved for each 8ºC temperature exceeds 60ºC.

Filtering

It is necessary to keep the level of contamination within a hydraulic system at an acceptable level to ensure trouble free operation. Filtration should always be specified at a level that protects the most sensitive item or component in the system.
