Section, function
The MR and MRE hydraulic motors are externally pressurised radial piston motors with a fixed swept volume.
DesignThe main components are housing (1), eccentric shaft (2), cover (3), control housing (4), roller bearing (5), cylinder (6), piston (7) and control (8.1; 8.2; 8.3).
Inlet and return of operating fluidThe operating fluid is fed to and returned from the motor via portsAorB.Thecylinderchambers(E)arefilledordrainedvia the control and the channels (D) in the housing (1).
Rotary group, torque generationThe cylinders and the pistons support themselves on the spherical areas of the eccentric shaft and the cover. It is the-reby possible for the piston and cylinder to align themselves, free from side forces, as the shaft rotates, together with hyd-rostatic unloading of the pistons and cylinders results in fric-tion being minimised and very high efficiencies are achieved.

The pressure in the cylinder chambers (E) acts directly on the excentric shaft. Of the 5 cylinders 2 or 3 are respectively connected with the supply or return sides.
ControlThe control consists of the control plate (8.1) and the distri-butor valve (8.2). Whilst the control plate is fixed to the hou-sing with pins, the distributor valve rotates at the same speed as the eccentric shaft. Drillings in the distributor valve form the connection to the control plate and to the piston cham-bers. The reaction ring (8.3) acts together with the compres-sion spring and the system pressure and effectively compen-sates for play. This results in a very high temperature shock resistance and constant performance values during the entire service life.
LeakagesThe low leakage within the housing F (1) which occurs at the piston and the control must be returned via the leakage port (C).

Flushing of housing
In order to achieve the maximum constant performance va-lues housing flushing is necessary (see diagrams on pages 9 to 19). Under special conditions as well as for the adherence to the recommended operating viscosity of 30 to 50 mm2/s in the
housing flushing of the motor housing outside of the forseen range may be necessary (see page 8). A simple method to check this is by measuring the surface temperature ϑA (as shown). The temperature insdie the housing is approx. ϑA + 3°C.

Pressure fluid technical dataPressure fluidSee catalogue sheet RE 07075 for detailed information regar-ding the selection of pressure fluids before carrying out any engineering/design work. Further notes on installation and commissioning can be found on page 36 of this catalogue sheet. When operating with HF pressure fluids or bio-degradable pressure fluids possible limitations to the technical data must be taken into consideration, please consult ourselves.
Operating viscosity rangeWe recommend that the operating viscosity is so selected (at operating temperature) that it lies in the optimum range of
νopt = optimum operating viscosity 30...50 mm2/sfor efficiency and service life, referring to the circulation tem-perature in closed circuit and the tank temperature in open circuit as well as the motor housing temperature (drain fluid temperature).
For the limiting conditions the following values are valid:νmin = 10 mm2/s in emergency, brieflyνmin = 18 mm2/s with reduced performance dataνmax = 1000 mm2/s briefly with cold start
Selection diagramChoosing the type of pressure fluida prerequisite for the selection of a pressure fluid is that the operating temperature in relation to the ambient tempera-ture is known. In closed circuits the circulation temperature, in open circuits the tank temperature. To achieve the maximum continuous power values the oil viscosity must be within the optimum operating viscosity range, referring to the inlet tem-perature as well as the drain oil temperature.
Shaft seal ring FKMSome fluids require the use of FKM seals and shaft seal rings (type: HFD ...). We recommend the use of FKM shaft seal rings with high operating temperatures in order to extend the service life.

Viscosity range to ISO 3448
Example: With an ambient temperature of X °C the operating tempera-ture settles to a temperature of 50 °C (closed circuit: circula-tion temperature, open circuit: tank temperature). For an opti-mum viscosity range this (νopt; raster field ) relates to a visco-sity class of VG 46 or VG 68; select: VG 68.The drain oil temperature which is influenced by the pressure and speed lies above the circulation or tank temperature. At no point in the system must this exceed 80 °C.If the above stated conditions cannot be maintained due to extreme operating conditions or high ambient temperatures we recommend that, also outside the foreseen range, hou-sing flushing is used (see diagram on pages 9 to 19), or con-sult ourselves.
Filtering of pressure fluidThe finer the filtration and the better the cleanliness class that can be achieved the longer the service life of the radial piston motors.To guarantee the functional safety of the radial piston motors a cleanliness class of at least 6 to SAE, ASTM, AIA 19/16/13 to ISO 4406 is necessary.
Leakage fluid pressureThe lower the speed and the leakage fluid pressure, the lon-ger the life of the shaft seal ring. The maximum permissible housing pressure is pmax = 5 barwhich is independent of the motor speed.For higher housing pressures a shaft seal which is suitable up to a pmax = 15 bar can be fitted (ordering code F). Further in-formation regarding housing flushing can be found on page 7.

Incremental transducer - introduction
Hydraulic motors that are fitted with an incremental transducer are suitable for use in all application areas where exact sen-sing of the motor shaft speed is required.All of the type MR Rexroth motors can be fitted with incremen-tal transduers. The solution is a package which includes the motor, incremental transducer control and incremental trans-ducer, all of wihich has protection to IP 67 (including the con-nection socket).
