Type

Data concerning RPM are based on maximum premitted peripheral velocity for the tapered roller bearings.

Sunfab SCM is a rangeof robust axial piston mo-tors especially suitable for mobile hydraulics.

Sunfab SCM is of the bent-axis type with spherical pis-tons. The design results in a compact motor with few mov-ing parts, high starting torque and high reliability.

Motor SCM 012-130 ISO3201 GB

The SCM covers the entire displacement range 12-130 cm3/rev at a maximum work-ing pressure of 40 MPa.

Sunfab SCM’s well dimen- sioned, double taperedroller bearings permit high shaft loads and lead to excel-lent speed characteristics.

Intermittent power data are based on maximum continuous speed and maximum working pressure.

Continuous power data are based on maximum output power with-out external cooling of the motor housing.

Intermittent duty is defined as follows: max 6 seconds per minute, e g peak RPM when unloading or accelerating.

Sunfab SCM’s high level of reliability is based on the choice of materials, hardening methods, surface structures and the quality assured ma-nufacturing process.

Factors affecting the choice of shaft seal include the hydraulic motor housing pressure and the drainage oil temperature.

Subject to design modifications without notice

Temp. Max. housing pressure MPa at rpm Motor SCM Code

The drainage oil should have a maximum temperature of 75 °C with a Nitrile shaft seal and 90 °C with a Viton shaft seal. These

temperatures must not be exceeded.Code according to Versions, main data.

Optimal force directionof radial load

Hydraulic fluids

High performance oils meeting ISO specifications – such as HM, DIN 51524-2HLP, or better – must be used. A min. viscosity of 10 cSt is required to keep the lubrica-tion at a safe level.

The ideal viscosity is 20 - 40 cSt.

Shaft loads

The life of the motor is highly dependent on thebearing life. The bearings are affected by operation conditions such as speed, pressure, oil viscosity and filtration.

Piping

Recommended oil velocity in pressure line max. 7 m/sec

Filtering

Cleanliness according to ISO norm 4406, code16/13.

External load on the shaft, as well as its size, direction and location also affect the bearing life. For calculation of bearing life in special applications, please contact Sunfab Hydraulics.

Choice of shaft seal

10 (12)

Q

Temperatures/Housing cooling

Excessive system temperature reduces the life of the shaft seal and can lower the oil viscosity below the re-commended level. A system temperature of 60 °C and a drain flow temperature of 90 °C must not be exceeded. Cooling/flushing of the motor housing can be needed to keep the drain flow temperature at an acceptable level.

Suggested flow: Motor SCM Flushing l/min Cont. RPM 012-034 2-8 ≥ 2800 040-064 4-10 ≥ 2500 084-130 6-12 ≥ 2200

Installation

• Themotorhousingshouldbefilledwithoiltoat least 50% before starting.

• Thedrainagepipeshouldbeconnectedtotopmost drainage outlet.

• Theotherendofthepipeshouldbeconnectedto the oil tank at a point below the oil level.

Qflush

Housing flushing can be built up with the help of a flushing valve or taken directly from the return line. When the return pressure is too low this is compensated for by a counter pressure valve.The tank line is connected to the highest point as in the figure.

D = displacement, cm3⁄revolution

n = speed, revolution⁄min

P = power, kW

Q = flow rate, litres⁄min

ηv = volumetric efficiency

ηhm = hydraulic-mechanical efficiency

ηt = overall efficiency = ηv x ηhm

M = torque, Nm

∆p = pressure difference between the hydraulic motor inlet and outlet, MPa

Useful formulaes

Required flow rate Q = litres⁄min.

Speed n = RPM

Torque M = Nm

Power P = kW
