Sauer-Danfoss is a world leader within production of low speed orbital motors with

high torque. We can offer more than 1600 different orbital motors, categorised in types,

variants and sizes (incl. different shaft versions).

The motors vary in size (rated displacement) from 8 cm 3 [0.50 in 3 ] to 800 cm 3 [48.9 in 3 ]

per revolution.

Speeds range up to approx. 2500 min -1 (rpm) for the smallest type and up to approx.

600 min -1 (rpm) for the largest type.

Maximum operating torques vary from 13 Nm [115 lbf•in] to 2700 Nm [24.000 lbf•in]

(peak) and maximum outputs are from 2,0 kW [2,7 hp] to 70 kW [95 hp].

Characteristic features:

• 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 eficiency

• 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 luids

A WIDE RANGE OF

ORBITAL MOTORS

(continued)

The programme is characterised by technical features appealing to a large number

of applications and a part of the programme is characterised by motors that can be

adapted to a given application. Adaptions comprise the following variants among others:

• Motors with corrosion resistant parts

• Wheel motors with recessed mounting lange

• OMP, OMR- motors with needle bearing

• OMR motor in low leakage version

• OMR motors in a super low leakage version

• Short motors without bearings

• Ultra short motors

• Motors with integrated positive holding brake

• Motors with integrated negative holding brake

• Motors with integrated lushing valve

• Motors with speed sensor

• Motors with tacho connection

• All motors are available with black inish paint

Planetary gears

Sauer-Danfoss complements the motor range with a complete programme of planetary

gears adapted to suit. The combination of motors and gears makes it possible to obtain

smooth running at fractional speeds and with torques up to 650 000 Nm

[5 800 000 lbf•in].

The Sauer-Danfoss orbital motors are used in the following application areas:

• Construction equipment

• Agricultural equipment

• Material handling & Lifting equipment

• Forestry equipment

• Lawn and turf equipment

• Special purpose

• Machine tools and stationary equipment

• Marine equipment

ORBITAL MOTORS

Detailed data on all Sauer-Danfoss motors can be found in our motor catalogue, which is

divided into 5 individual subcatalogues:

• General information on Sauer-Danfoss orbital motors: function, use, selection of

hydraulic motor, hydraulic systems, etc.

• Technical data on small motors: OML and OMM

• Technical data on medium sized motors: OMP, OMR, OMH and OMEW

• Technical data on medium sized motors: DH and DS

• Technical data on large motors: OMS, OMT and OMV

• Technical data on large motors: TMK

• Technical data on large motors: TMT

A general survey brochure on Sauer-Danfoss orbital motors gives a quick motor

reference based on power, torque, speed and capabilities.
