A WIDE RANGE OF ORBITAL MOTORS
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 cm3 [0.50 in3] to 800 cm3 [48.9 in3] 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 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

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. • OMS can be found on pages 14-18 • OMT can be found on pages 42-44 • OMV can be found on pages 65-67 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" DHMH.PK.100.G2.02 520L0232. 520L0407

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.

OMS Technical Information OMSS 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. 520L0407

OMT Technical Information OMTS 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 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. 520L0407

OMV Technical Information OMVS 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. 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. 520L0407
