Orbital Motors Introduction
Danfoss is a world leader within production of low speed orbital motors with high torque. We can offer
more than 1500 different orbital motors, categorized in types, variants and sizes (including different shaft
versions).
The motors size vary (rated displacement) from 130 to 800 cm

The bar diagrams above are useful for a quick selection of relevant motor size for the application. The
final motor size can be determined by using the function diagram for each motor size: see OMT Function
diagrams on page 14, or OMV function diagrams on page 45.
The function diagrams are based on actual tests on a representative number of motors from our
production. The diagrams apply to a return pressure between 5 and 10 bar [75 and 150 psi] when using
mineral based hydraulic oil with a viscosity of 35 mm

/s [165 SUS] and a temperature of 50°C [120°F].
