General Description

Series 51 and 51-1 variable displacement motors arebent axis design units, incorporating spherical pistons.

These motors are designed primarily to be combinedwith other products in closed circuit systems to transferand control hydraulic power. Series 51 and 51-1 motorshave a large maximum / minimum displacement ratio(5:1) and high output speed capabilities. SAE, cartridge,and DIN flange configurations are available.

A complete family of controls and regulators is availableto fulfill the requirements of a wide range of applications.

Motors normally start at maximum displacement. Thisprovides maximum starting torque for high acceleration.

The controls may utilize internally supplied servo pres-sure. They may be overridden by a pressure compensa-tor which functions when the motor is operating in motorand pump modes. A defeat option is available to disablethe pressure compensator override when the motor isrunning in pump mode.

The pressure compensator option features a low pres-sure rise (short ramp) to ensure optimal power utilizationthroughout the entire displacement range of the motor.The pressure compensator is also available as a stand-alone regulator.

• The series 51 and 51-1 motors – Advanced technology today

Under normal operating conditions, case pressure mustnot exceed the rated pressure. Momentary case pres-sure exceeding this rating is acceptable under cold startconditions, but still must stay below the maximumpressure rating. The minimum pressure providesproper lubrication at high speeds. Operation with casepressure in excess of these limits may result in externalleakage due to damage to seals, gaskets, and/or hous-ings.

Rated Speed is the speed limit recommended at fullpower condition and is the highest value at which normallife can be expected

Maximum Speed is the highest operating speed permit-ted and cannot be exceeded without reduction in the lifeof the product or risking immediate failure and loss ofdriveline power (which may create a safety hazard). In therange between rated and maximum speed please con-tact your SAUER-SUNDSTRAND representative.

WARNINGThe loss of hydrostatic drive line power in anymode of operation (e.g., forward, reverse, or “neu-tral” mode) may cause the loss of hydrostaticbraking capacity. A braking system, redundant tothe hydrostatic transmission must, therefore, beprovided which is adequate to stop and hold thesystem should the condition develop.

Pressure Limits

System pressure is the dominant operating variableaffecting hydraulic unit life. High pressure, which resultsfrom high load, reduces expected life in a manner similarto the affects of high load on other mechanical assem-blies such as engines and gear boxes. There are load-to-life relationships for the rotating group and for the shaftanti-friction bearings.

Continuous pressure is the pressure at which the hydro-static system could operate continuously and stillachieve acceptable hydrostatic life. This pressure levelvaries depending on operating speed, and on the liferequirements for a particular application. While mostmobile applications require system pressure to varywidely during operation, a “weighted average” pressurecan be derived from a machine duty cycle. (A duty cycle isa means of quantifying the pressure and speed demandsof a particular system on a percent time basis). Once aduty cycle has been determined or estimated for aspecific application, contact your SAUER-SUND-STRAND representative for system life ratings for theapplication.

Maximum delta pressure is the highest intermittentpressure allowed, and is the relief valve setting. It isdetermined by the maximum machine load demand. Formost systems, the load should move at this pressure.

Maximum pressure is assumed to occur a small percent-age of operating time, usually less than 2% of the total.Both the continuous and maximum pressure limits mustbe satisfied to achieve the expected life.

Minimum low pressure must maintained under alloperating conditions to avoid cavitation.

An integral non-adjustable loop flushing valve is incorpo-rated into all these motors. Installations that require fluidto be removed from the low pressure side of the systemcircuit because of cooling requirements or contaminationremoval will benefit from loop flushing.

The integral loop flushing valve is equipped with anorificed charge pressure relief valve designed with acracking pressure of 1.6 Mpa [16 bar] (232 psi). Valvesare available with several orifice sizes to meet theflushing flow requirements of all system operating condi-tions.

The total system charge pump flow should be of sufficientvolume to accommodate:

• The number of motors in the system• System efficiency under worst case conditions• Pump control requirements• External needs

Although charge pump sizing requires the considerationof many system variables, the following table gives arecommendation of what charge pump displacementmay be required to accommodate the flushing flow ofeach available charge relief valve orifice.

Ratings and data are based on operating with hydraulicfluids containing oxidation, rust and foam inhibitors.These fluids must possess good thermal and hydrolyticstability to prevent wear, erosion and corrosion of theinternal components.

Fire resistant fluids are also suitable at modified operat-ing conditions. Please see SAUER-SUNDSTRAND pub-lication 697581 or BLN-9887 for more information. Referto publication ATI-9101E for information relating to biode-gradable fluids.

It is not permissible to mix hydraulic fluids. For moreinformation contact your SAUER-SUNDSTRAND repre-sentative.

Suitable Hydraulic fluids:

• Hydraulic fluids per DIN 51 524, part 2 (HLP)• Hydraulic fluids per DIN 51 524, part 3 (HVLP)• API CD, CE and CF engine fluids per SAE J183• M2C33F or G automatic transmission fluids (ATF)• Dexron II (ATF), which meets the Allison C3- and

Caterpillar TO-2 test• Agricultural multi purpose oil (STOU)• Premium turbine oils

Temperature and viscosity requirements must be concur-rently satisfied. The data shown in the tables assumepetroleum-based fluids, are used.

The high temperature limits apply at the hottest point inthe transmission, which is normally the motor case drain.The system should generally be run at or below the ratedtemperature. The maximum temperature is based onmaterial properties and should never be exceeded.

Cold oil will generally not affect the durability of thetransmission components, but it may affect the ability toflow oil and transmit power; therefore temperaturesshould remain 16°C (30°F) above the pour point of thehydraulic fluid. The minimum temperature relates to thephysical properties of component materials.

For maximum unit efficiency and bearing life the fluidviscosity should remain in the recommended operatingrange. The minimum viscosity should be encounteredonly during brief occasions of maximum ambient tem-perature and severe duty cycle operation. The maximumviscosity should be encountered only at cold start.

Heat exchangers should be sized to keep the fluid withinthese limits. Testing to verify that these temperature limitsare not exceeded is recommended.

E700200T1 Filter βx-ratio is a measure of filter efficiency defined by ISO 4572. It is

defined as the ratio of the number of particles greater than a givendiameter (“x” in µm) upstream of the filter to the number of theseparticles downstream of the filter.

To prevent premature wear, it is imperative that only cleanfluid enter the hydrostatic transmission circuit. A filtercapable of controlling the fluid cleanliness to ISO 4406Class 18/13 (SAE J1165) or better under normal operat-ing conditions is recommended.

The filter may be located either on the inlet (suctionfiltration) or discharge (charge pressure filtration) side ofthe charge pump. The selected filtration system mustmaintain a cleanliness level of 18/13 per ISO 4406.

The selection of a filter depends on a number of factorsincluding the contaminant ingression rate, the genera-tion of contaminants in the system, the required fluidcleanliness, and the desired maintenance interval. Filtersare selected to meet the above requirements using ratingparameters of efficiency and capacity.

Filter efficiency may be measured with a Beta ratio1 (βX).For simple suction-filtered closed circuit transmissionsand open circuit transmissions with return line filtration, afilter with a β-ratio within the range of β35-45 = 75 (β10 ≥ 2) orbetter has been found to be satisfactory. For some opencircuit systems, and closed circuits with cylinders beingsupplied from the same reservoir, a considerably higher

filter efficiency is recommended. This also applies tosystems with gears or clutches using a common reservoir.For these systems, a filter within the range of β15-20 = 75(β10 ≥ 10) or better is typically required.

Since each system is unique, the filtration requirement forthat system will be unique and must be determined bytest in each case. It is essential that monitoring ofprototypes and evaluation of components and perfor-mance throughout the test program be the final criteria forjudging the adequacy of the filtration system. See publi-cation BLN-9887 or 697581 and ATI-E9201 for moreinformation.

WARNINGThe loss of hydrostatic drive line power in anymode of operation (e.g., forward, reverse, or “neu-tral” mode) may cause the loss of hydrostaticbraking capacity. A braking system, redundant to

the hydrostatic transmission must, therefore, beprovided which is adequate to stop and hold thesystem should the condition develop.

S000 001E

The function of the reservoir is to remove air and toprovide make up fluid for volume changes associatedwith fluid expansion or contraction, possible cylinderflow, and minor leakage.

The reservoir should be designed to accommodatemaximum volume changes during all system operatingmodes and to promote deaeration of the fluid as it passesthrough the tank.

A suggested minimum reservoir volume equal to 1/2charge pump flow/min. This allows 30 seconds fluid dwellfor removing entrained air at the maximum return flow.

This is usually adequate to allow for a closed reservoir(no breather) in most applications. The reservoir outlet tothe charge pump inlet should be above the bottom of thereservoir to take advantage of gravity separation andprevent large foreign particles from entering the chargeinlet line.

The reservoir inlet (fluid return) should be positioned sothat the flow to the reservoir is discharged below thenormal fluid level, and also directed into the interior of thereservoir for maximum dwell and efficient deaeration.

Allowable External Shaft Load, when Shaft Load Distance is different from Standard

Use this formula to calculate maximum allowable radialload when max. shaft load distance (X2) is different from(X1):

Note:

(X2) is the actual distance of (Fr) from the mounting flangeto the load for a given application. If X2 < X1, (Fr) couldalso be calculated by the first equation, but in addition thebearing life has to be checked.

Contact your SAUER-SUNDSTRAND representative forload ratings of specific shafts or when the load orienta-tion deviates more than 35° in either direction from theoptimum.

An optional speed sensor for direct measurement ofspeed is available. This sensor may also be used tosense the direction of rotation.

A special magnetic speed pick-up ring is pressed ontothe outside diameter of the shaft and a Hall effect sensoris located in the motor housing. The sensor acceptssupply voltage and outputs a digital pulse signal inresponse to the speed of the ring. The output changes itshigh/low state as the north and south poles of thepermanently magnetized speed ring pass by the face ofthe sensor. The digital signal is generated at frequenciessuitable for microprocessor based controls.

The sensor is available with different connectors (seebelow).

Displacement is regulated automatically between mini-mum displacement and maximum displacement in re-sponse to system pressure.

Regulator start = minimum displacementRegulator end = maximum displacement

Regulator start pressure is adjustable from 11 to 37 MPa[110 to 370 bar] (1 600 to 5 370 psi).

Pressure ramp from regulator start pressure (with motorat minimum displacement) until maximum displacement isreached is less than 1 MPa [10 bar] (145 psi). Thisensures optimal power utilization throughout the entiredisplacement range of the motor.

A shuttle valve ahead of the pressure compensatorprevents operation in the deceleration direction (whenmotor is running in pump mode). This is designed toprevent rapid or uncontrolled deceleration while thevehicle/machine is slowing down.

Pressure compensator override with brake pressure de-feat is mainly used in systems with pumps having electricor hydraulic proportional controls or automotive controls.

A solenoid-switched valve ahead of the pressure compen-sator prevents operation in the deceleration direction(when motor is running in pump mode). This is designedto prevent rapid or uncontrolled deceleration while thevehicle/machine is slowing down.

Pressure compensator functions when the motor is run-ning in motor mode as well as in pump (deceleration)mode.

Pressure Compensator Control TA

Displacement is regulated automatically between mini-mum displacement and maximum displacement in re-sponse to system pressure.

Regulator start = minimum displacementRegulator end = maximum displacement

Regulator start pressure is adjustable from 11 to 37 MPa[110 to 370 bar] (1 600 to 5 370 psi).

Pressure ramp from regulator start pressure (with motorat minimum displacement) until maximum displacement isreached is less than 1 MPa [10 bar] (145 psi). Thisensures optimal power utilization throughout the entiredisplacement range of the motor.

Hydraulic Two-Position Control TH

Displacement can be changed hydraulically under loadfrom minimum displacement to maximum displacementand vice versa.

Pressure on port X1 must be equal to the pressure of themotor case ± 0.02 MPa, [0.2 bar], (2.9 psi) this keeps themotor at minimum displacement.

Pressure 1.0 MPa, [10 bar], (145 psi) to 3.5 MPa, [35 bar],(508 psi) above case pressure on port X1 strokes themotor to maximum displacement

Control Operation TH

Pressure Compensator Override (PCOR)

The control can be overridden by PCOR using high looppressure.

When the PCOR activates, the motor displacement in-creases to maximum. Pressure ramp from PCOR startpressure (with motor at minimum displacement) untilmaximum displacement is reached is less than 1 MPa[10 bar] (145 psi). This ensures optimal power utilizationthroughout the entire displacement range of the motor.

PCOR start pressure is adjustable from 11 to 37 MPa [110to 370 bar] (1 600 to 5 370 psi).

Pressure Compensator (PCOR) andBrake Pressure Defeat

Electrohydraulic Proportional Control D7, D8

Displacement can be changed electrohydraulically underload in response to an electrical signal from minimumdisplacement to maximum displacement and vice versa.The displacement changes proportional to the electricalsignal. The electrical signal must be a pulse-width modu-lated (PWM) signal, (f = 100...200 Hz).

Solenoid not energized = maximum displacementSolenoid energized = minimum displacement

Servo pressure supply = external pressure at X3min. pressure = 2.5 MPa [25 bar] (363 psi)max. pressure = 5 MPa [50 bar] (725 psi)

Ports:A, B = Main pressure linesL1, L2 = Drain linesM1, M2 = Gauge port for A and BM3, M4 = Gauge port servo pressureX3 (M5) = Servo pressure supplyM7 = Gauge port control pressureXA, XB = Control pressure ports

A shuttle valve ahead of the pressure compensatoroverride prevents PCOR operation in the decelerationdirection (when motor is running in pump mode). This isdesigned to prevent rapid or uncontrolled decelerationwhile the vehicle/machine is slowing down.


The pressure compensator override functions when themotor is running in motor mode as well as in pump(deceleration) mode.

Pressure Compensator OverrideConfiguration: A1 with Brake Pressure Defeat

Pressure Compensator OverrideConfiguration: A2 without Brake Pressure Defeat
