wide range of Orbital Motors 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, different orbital motors, categorised in types, variants and sizes (including different shaft versions). The motors vary in size (rated displacement) from 8 cm³ [.5 in³] to 8 cm³ [48.9 in³] per revolution. Speeds range up to approximate 2,5 min -1 (rpm) for the smallest type and up to approximate 6 min -1 (rpm) for the largest type. Maximum operating torques vary from 13 N m [115 lbf in] to 2,7 N m [24, lbf in] (peak) and maximum outputs are from 2. kw [2.7 hp] to 7 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 a part of the programme is characterised by motors that can be adapted to a given application. daptions comprise the following variants among others: 6 52L47 Rev F November 214

Data survey OMS can be found here OMT can be found here OMV can be found here 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 1 bar [75 and 15 psi] when using mineral based hydraulic oil with a viscosity of 35 mm²/s [165 SUS] and a temperature of 5 C [12 F].

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. 633B923) 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. 151F133) 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.

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. 46 52L47 Rev F November 214
