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].
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
•

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.

OMP and OMPW: see OMP function diagrams
•
OMR and OMRW: see OMR function diagrams on page 55
•
OMH: see OMH function diagrams on page 85
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
2
/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 on OMP N can be offered in needle bearings. These bearings and the recessed mounting
flange allow a higher permissible radial load in comparison to OMP motors.
The permissible radial load on the shaft is shown for different speeds as a function of the distance from
the mounting flange to the point of load application.

Curve A indicates the max. radial shaft load. Any shaft load exceeding the values quoted in curve A will
involve risk of breakage.
The other curves apply to a B10 bearing life of 2000 hours at the number of revolutions indicated by the
curve letter. Mineral based hydraulic oil with a sufficient content of anti-wear additives must be used.
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.

The output shaft on OMPW can be offered in slide bearings similar to the other OMP-motors. The
permissible higher radial load is therefore due to the recessed mounting flange moving the point of load
closer to the motor bearings.
The permissible radial load on the shaft is shown for different speeds as a function of the distance from
the mounting flange to the point of load application.
The curves are not based on calculations of B10 bearing life. They represent absolute limits that must not
be exceeded.
Curve A indicates the max. radial shaft load. Any shaft load exceeding the values quoted in curve A will
involve risk of breakage.

1)
This brake is to be used only as a passive parking brake. It may not be used for dynamic braking.
2)
Brake motors must always have a drain line. The brake release pressure is the difference between the pressure in the brake release line and the
pressure in the drain line.
OMR F function
In normal condition where there is no pressure on the integrated brake in OMR, i.e. the brake is applied.
The brake is released when hydraulic pressure of 21 bar [300 psi] min. is applied to the brake release port
(1).
The pressure forces the piston (2) against the springs (3 and 4) disengaging the outer and inner discs (5
and 6) from each other so that the cardan shaft (7) and consequently output shaft (8) become free to
rotate.
If the pressure on the brake release port is reduced to less than 21 bar [300 psi], the springs force the
piston and pressure pad (9) against the brake discs and the cardan shaft/output shaft begin to lock up.

The output shaft on OMR N and OMR NF runs in needle bearings. These bearings and the recessed
mounting flange allow a higher permissible radial load in comparison to OMR motors with slide bearings.
The permissible radial load on the shaft is shown for different speeds as a function of the distance from
the mounting flange to the point of load application.
Curve A shows max. radial shaft load. Any shaft load exceeding the values quoted in the curve will
involve a risk of breakage.
The other curves apply to a B10 bearing life of 2000 hours at the number of revolutions indicated by the
curve letter. Mineral based hydraulic oil with a sufficient content of anti-wear additives must be used.
Bearing life calculations can be made using the explanation and formula provided in the
chapter »Bearing dimensioning« in the technical information Orbital Motors General 520L0232.
