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 offer
more than 3,000 different orbital motors, categorised in types, variants and sizes (including different shaft
versions).
The motors vary in size (rated displacement) from 8 cm³ [0.50 in³] to 800 cm³ [48.9 in³] 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 N•m [115 lbf•in] to 2,700 N•m [24,000 lbf•in] (peak) and
maximum outputs are from 2.0 kW [2.7 hp] to 70 kW [95 hp].

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 mm²/s [165 SUS] and a temperature of 50°C [120°F]. For
further explanation concerning how to read and use the function diagrams, please consult the paragraph
"Selection of motor size" in the technical information "General Orbital motors" 520L0232.

The output shaft runs in tapered roller bearings that permit high axial and radial forces.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of the distance from
the 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 rated
output torque, when mineral-based hydraulic oil with a sufficient content of anti-wear additives, is used.
For 3,000,000 shaft revolutions or 500 hours – increase these shaft loads with 52%.

Installing the OMSS
The cardan shaft of the OMSS motor acts as an “output shaft”. Because of the movement of the shaft, no
seal can be fitted at the shaft output.
Internal oil leakage from the motor will therefore flow into the attached component.
During start and operation it is important that the spline connection and the bearings in the attached
component receive oil and are adequately lubricated. To ensure that the spline connection receives
sufficient oil, a conical sealing ring between the shaft of the attached component and the motor
intermediate plate is recommended. This method is used in the OMS.
The conical sealing ring (code. no. 633B9023) is supplied with the motor.
To ensure that oil runs to the bearings and other parts of the attached component, the stop plate must
have a hole in it (see fig. below).
We recommend an O-ring between motor and attached component. The O-ring (code no. 151F1033) is
supplied with the motor. If motor and attached component have been separated, remember to refill
before starting up. Fill the oil through the drain connection.

Drain Connection on OMSS or Attached Component
A drain line ought to be used when pressure in the return line can exceed the permissible pressure on the
shaft seal of the attached component.
The drain line can be connected at two different points:
1) at the motor drain connection
2) at the drain connection of the attached component.
If a drain line is fitted to the attached component, it must be possible for oil to flow freely between motor
and attached component.
The drain line must be led to the tank in such a way that there is no risk of the motor and attached
component being drained of oil when at rest.
The maximum pressure in the drain line is limited by the attached component and its shaft seal.

The output shaft runs in tapered roller bearings that permit high axial and radial forces.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of the distance from
the 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 rated
output torque, when mineral-based hydraulic oil with a sufficient content of anti-wear additives, is used.
For 3,000,000 shaft revolutions or 500 hours – increase these shaft loads with 52%.
The dash curve shows max. radial shaft load. Any shaft load exceeding the values shown in the curve will
involve a risk of breakage.
Bearing life calculations can be made using the explanation and formula provided in the chapter "Bearing
dimensioning" in the technical information "General Orbital motors" 520L0232.

Installing the OMTS
The cardan shaft of the OMTS motor acts as an “output shaft”. Because of the movement of the shaft, no
seal can be fitted at the shaft output.
Internal oil leakage from the motor will therefore flow into the attached component.
During start and operation it is important that the spline connection and the bearings in the attached
component receive oil and are adequately lubricated. To ensure that the spline connection receives
sufficient oil, a conical sealing ring between the shaft of the attached component and the motor
intermediate plate is recommended. This method is used in the OMT.
The conical sealing ring (code. no. 633B9022) is supplied with the motor.
To ensure that oil runs to the bearings and other parts of the attached component, the stop plate must
have a hole in it (see fig. below).
We recommend an O-ring between motor and attached component. The O-ring (code no. 151B1040) is
supplied with the motor. If motor and attached component have been separated, remember to refill
before starting up. Fill the oil through the drain connection.

Drain Connection on OMTS or Attached Component
A drain line ought to be used when pressure in the return line can exceed the permissible pressure on the
shaft seal of the attached component.
The drain line can be connected at two different points:
1) at the motor drain connection
Technical Information
OMS, OMT and OMV Orbital Motors
OMTS
520L0407 • Rev FA • November 2014 77
2) at the drain connection of the attached component.
If a drain line is fitted to the attached component, it must be possible for oil to flow freely between motor
and attached component.
The drain line must be led to the tank in such a way that there is no risk of the motor and attached
component being drained of oil when at rest.
The maximum pressure in the drain line is limited by the attached component and its shaft seal.

The output shaft runs in tapered roller bearings that permit high axial and radial forces.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of the distance from
the 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 rated
output torque, when mineral-based hydraulic oil with a sufficient content of anti-wear additives, is used.
For 3,000,000 shaft revolutions or 500 hours – increase these shaft loads with 52%.
The dash curve shows max. radial shaft load. Any shaft load exceeding the values shown in the curve will
involve a risk of breakage.
Bearing life calculations can be made using the explanation and formula provided in the chapter "Bearing
dimensioning" in the technical information "General Orbital motors" 520L0232.

Installing the OMVS
The cardan shaft of the OMVS motor acts as an “output shaft”. Because of the movement of the shaft, no
seal can be fitted at the shaft output.
Internal oil leakage from the motor will therefore flow into the attached component.
During start and operation it is important that the spline connection and the bearings in the attached
component receive oil and are adequately lubricated. To ensure that the spline connection receives
sufficient oil, a conical sealing ring between the shaft of the attached component and the motor
intermediate plate is recommended. This method is used in the OMV.
The conical sealing ring (code. no. 633B9021) is supplied with the motor.
To ensure that oil runs to the bearings and other parts of the attached component, the stop plate must
have a hole in it (see fig. below).
We recommend an O-ring between motor and attached component. The O-ring (code no. 151B1041) is
supplied with the motor. If motor and attached component have been separated, remember to refill
before starting up. Fill the oil through the drain connection.

Drain connection on OMVS or attached component
A drain line ought to be used when pressure in the return line can exceed the permissible pressure on the
shaft seal of the attached component.
The drain line can be connected at two different points:
1) at the motor drain connection
2) at the drain connection of the attached component.
If a drain line is fitted to the attached component, it must be possible for oil to flow freely between motor
and attached component.
