Characteristic, features and application areas of Orbital Motors
Danfoss is a world leader within production of low speed orbital motors with high torque. We can offermore than 3,000 different orbital motors, categorised in types, variants and sizes (including different shaftversions).
The motors vary in size (rated displacement) from 8 cm [0.50 in] to 800 cm [48.9 in] per revolution.
Speeds range up to approximate 2,500 min-1 (rpm) for the smallest type and up to approximate 600 min-1
(rpm) for the largest type.
Maximum operating torques vary from 13 Nm [115 lbfin] to 2,700 Nm [24,000 lbfin] (peak) andmaximum outputs are from 2.0 kW [2.7 hp] to 70 kW [95 hp].
Characteristic features of Danfoss Orbital Motors
Smooth running over the entire speed range Constant operating torque over a wide speed range High starting torque High return pressure without the use of drain line (High pressure shaft seal) High efficiency Long life under extreme operating conditions Robust and compact design High radial and axial bearing capacity For applications in both open and closed loop hydraulic systems Suitable for a wide variety of hydraulics fluids
Technical features of Danfoss Orbital Motor
The programme is characterised by technical features appealing to a large number of applications and apart of the programme is characterised by motors that can be adapted to a given application. Adaptionscomprise the following variants among others:

The bar diagrams above are useful for a quick selection of relevant motor size for the application. Thefinal motor size can be determined by using the function diagram for each motor size. OMSW can be found here: Function diagrams on page 13.
The function diagrams are based on actual tests on a representative number of motors from ourproduction. The diagrams apply to a return pressure between 5 and 10 bar [75 and 150 psi] when usingmineral based hydraulic oil with a viscosity of 35 mm2/s [165 SUS] and a temperature of 50C [120F]. Forfurther explanation concerning how to read and use the function diagrams, please consult the paragraph"Selection of motor size" in the technical information "General" 520L0232.

Permissible shaft load for OMSW
Mounting flange: Wheel / Shaft: All shaft types
Permissible radial shaft load
The output shaft runs in tapered roller bearings that permit high axial and radial forses.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of the distance fromthe mounting flange to the point of load application.
The curve is based on B10 Bearing life (2000 hours or 12 000 000 shaft revolutions at 100 min-1) at ratedoutput torque, when mineral-based hydraulic oil with a sufficient content of anti-wear additives, is used.
