General Description
General Description
Series 51 and 51-1 variable displacement motors are bent axis design units, incorporating
spherical pistons.
These motors are designed primarily to be combined with other products in closed
circuit systems to transfer and control hydraulic power. Series 51 and 51-1 motors have
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 available to fulfill the requirements of
a wide range of applications.
Motors normally start at maximum displacement. This provides maximum starting
torque for high acceleration.
The controls may utilize internally supplied servo pressure. They may be overridden by
a pressure compensator which functions when the motor is operating in motor and
pump modes. A defeat option is available to disable the pressure compensator override
when the motor is running in pump mode.
The pressure compensator option features a low pressure rise (short ramp) to ensure
optimal power utilization throughout 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

case pressure
Under normal operating conditions, case pressure must not exceed the rated pressure.
Momentary case pressure exceeding this rating is acceptable under cold start conditions,
but still must stay below the maximum pressure rating. The minimum pressure
provides proper lubrication at high speeds. Operation with case pressure in excess of
these limits may result in external leakage due to damage to seals, gaskets, and/or
housings.

Rated Speed is the speed limit recommended at full power condition and is the highest
value at which normal life can be expected.
Maximum Speed is the highest operating speed permitted and cannot be exceeded
without reduction in the life of the product or risking immediate failure and loss of
driveline power (which may create a safety hazard). In the range between rated and
maximum speed please contact your Sauer-Danfoss representative.
Warning: The loss of hydrostatic drive line power in any mode of operation (e.g., forward,
reverse, or “neutral” mode) may cause the loss of hydrostatic braking capacity. A braking
system, redundant to the hydrostatic transmission must, therefore, be provided which is
adequate to stop and hold the system should the condition develop.

pressure limits
System pressure is the dominant operating variable affecting hydraulic unit life. High
pressure, which results from high load, reduces expected life in a manner similar to the
affects of high load on other mechanical assemblies such as engines and gear boxes.
There are load-to-life relationships for the rotating group and for the shaft anti-friction
bearings.
Continuous pressure is the pressure at which the hydrostatic system could operate
continuously and still achieve acceptable hydrostatic life. This pressure level varies
depending on operating speed, and on the life requirements for a particular application.
While most mobile applications require system pressure to vary widely during operation,
a “weighted average” pressure can be derived from a machine duty cycle. (A duty cycle
is a means of quantifying the pressure and speed demands of a particular system on a
percent time basis). Once a duty cycle has been determined or estimated for a specific
application, contact your Sauer-Danfoss representative for system life ratings for the
application.
Maximum delta pressure is the highest intermittent pressure allowed, and is the relief
valve setting. It is determined by the maximum machine load demand. For most systems,
the load should move at this pressure.
Maximum pressure is assumed to occur a small percentage of operating time, usually
less than 2 % of the total. Both the continuous and maximum pressure limits must be
satisfied to achieve the expected life.
Minimum low pressure must maintained under all operating conditions to avoid
cavitation.

An integral non-adjustable loop flushing valve is incorporated into all these motors.
Installations that require fluid to be removed from the low pressure side of the system
circuit because of cooling requirements or contamination removal will benefit from loop
flushing.
The integral loop flushing valve is equipped with an orificed charge pressure relief valve
designed with a cracking pressure of 16 bar [232 psi]. Valves are available with several
orifice sizes to meet the flushing flow requirements of all system operating conditions.

hydraulic fluids
Ratings and data are based on operating with hydraulic fluids containing oxidation, rust
and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to
prevent wear, erosion and corrosion of the internal components.
Fire resistant fluids are also suitable at modified operating conditions. Please see
Sauer-Danfoss literature Hydraulic Fluids and Lubricants Technical Information for more
information.

Agricultural multi purpose oil (STOU)
Premium turbine oils
(for Premium turbine oils contact your Sauer-Danfoss representative).
Temperature and viscosity requirements must be concurrently satisfied. The data shown
in the tables assume petroleum-based fluids, are used.
The high temperature limits apply at the hottest point in the transmission, which is
normally the motor case drain. The system should generally be run at or below the rated
temperature. The maximum temperature is based on material properties and should
never be exceeded.
Cold oil will generally not affect the durability of the transmission components, but it
may affect the ability to flow oil and transmit power; therefore temperatures should
remain 16 °C [30 °F] above the pour point of the hydraulic fluid. The minimum
temperature relates to the physical properties of component materials.
For maximum unit efficiency and bearing life the fluid viscosity should remain in
the recommended operating range. The minimum viscosity should be encountered
only during brief occasions of maximum ambient temperature and severe duty cycle
operation. The maximum viscosity should be encountered only at cold start.
Heat exchangers should be sized to keep the fluid within these limits. Testing to verify
that these temperature limits are not exceeded is recommended.

To prevent premature wear, it is imperative that only clean fluid enter the hydrostatic
transmission circuit. A filter capable of controlling the fluid cleanliness to ISO 4406 Class
22/18/13 (SAE J1165) or better under normal operating conditions is recommended.
The filter may be located either on the inlet (suction filtration) or discharge (charge pressure filtration) side of the charge pump. The selected filtration system must maintain a
cleanliness level of 22/18/13 per ISO 4406.
The selection of a filter depends on a number of factors including the contaminant
ingression rate, the generation of contaminants in the system, the required fluid
cleanliness, and the desired maintenance interval. Filters are selected to meet the above
requirements using rating parameters of efficiency and capacity.
Filter efficiency may be measured with a Beta ratio1) (βX). For simple suction-filtered
closed circuit transmissions and open circuit transmissions with return line filtration,
a filter with a β-ratio within the range of β35-45 = 75 (β10 ≥ 2) or better has been found to
be satisfactory. For some open circuit systems, and closed circuits with cylinders being
supplied from the same reservoir, a considerably higher filter efficiency is recommended.
This also applies to systems with gears or clutches using a common reservoir. For these
systems, a charge pressure or return filtration system with a filter β-ratio in the range of
β15-20 = 75 (β10 ≥ 10) or better is typically required.
Since each system is unique, the filtration requirement for that system will be unique
and must be determined by test in each case. It is essential that monitoring of
prototypes and evaluation of components and performance throughout the test
program be the final criteria for judging the adequacy of the filtration system.
Please see Sauer-Danfoss literature Hydraulic Fluids and Lubricants Technical Information
for more information.

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 given diameter (“x” in µm) upstream of the filter to the number of these particles

braking system
Warning: The loss of hydrostatic drive line power in any mode of operation (e.g., forward,
reverse, or “neutral” mode) may cause the loss of hydrostatic braking capacity. A braking
system, redundant to the hydrostatic transmission must, therefore, be provided which is
adequate to stop and hold the system should the condition develop.
reservoir
The function of the reservoir is to remove air and to provide make up fluid for volume
changes associated with fluid expansion or contraction, possible cylinder flow, and minor
leakage.
The reservoir should be designed to accommodate maximum volume changes during
all system operating modes and to promote deaeration of the fluid as it passes through
the tank.
A minimum reservoir volume equal to 1/2 to 1 1/2 times charge pump flow/min is
suggested. This allows 30 seconds fluid dwell for 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 to the charge pump inlet should be above the
bottom of the reservoir to take advantage of gravity separation and prevent large foreign
particles from entering the charge inlet line.
The reservoir inlet (fluid return) should be positioned so that the flow to the reservoir
is discharged below the normal fluid level, and also directed into the interior of the
reservoir for maximum dwell and efficient deaeration.

Speed Sensor
An optional speed sensor for direct measurement of speed is available. This sensor may
also be used to sense the direction of rotation.
A special magnetic speed pick-up ring is pressed onto the outside diameter of the shaft
and a Hall effect sensor is located in the motor housing. The sensor accepts supply
voltage and outputs a digital pulse signal in response to the speed of the ring. The
output changes its high/low state as the north and south poles of the permanently
magnetized speed ring pass by the face of the sensor. The digital signal is generated at
frequencies suitable for microprocessor based controls.
The sensor is available with different connectors (see below).
The SAE and DIN flange motors use a flat end speed sensor. The cartridge flange motors
use a conical end speed sensor.

Hydraulic Two-Position Control N1NN
Displacement changes from maximum displacement to minimum displacement position,
under load, as control pressure at port X1 (M3) is equal to low pressure or higher.
Control Pressure:
No pressure on port X1 (M3)
= maximum displacement
Control pressure on port X1 (M3) = minimum displacement.
Max. control pressure X1(M3)
= 50 bar [725 psi]
The graph shows the necessary external and internal (= low system pressure) control
pressure X1, which is needed to stroke the motor depending on high system pressure.

Displacement can be changed hydraulically under load from minimum displacement to
maximum displacement and vice versa.
Pressure on port X1 must be equal to the pressure of the motor case ± 0.2 bar, [3.0 psi]
this keeps the motor at minimum displacement.
Pressure 10 bar, [145 psi] to 35 bar, [510 psi] above case pressure on port X1 strokes the
motor to maximum displacement.
Pressure Compensator Override (PCOR)
The control can be overridden by PCOR using high loop pressure.
When the PCOR activates, the motor displacement increases toward maximum.
Pressure ramp from PCOR start pressure (with motor at minimum displacement)
until maximum displacement is reached is less than 10 bar [145 psi].
This ensures optimal power utilization throughout the entire displacement range of the
motor.
PCOR start pressure is adjustable from 130 to 370 bar [1890 to 5370 psi].

Displacement can be changed electrohydraulically under load from minimum
displacement to maximum displacement and vice versa, by using a solenoid. When
the solenoid is energized the motor has maximum displacement and the pressure
compensator does not function.
Solenoid not energized = minimum displacement
Solenoid energized
= maximum displacement
Pressure Compensator Override (PCOR)
The control can be overridden by PCOR using high loop pressure.
When the PCOR activates, the motor displacement increases toward maximum.
Pressure ramp from PCOR start pressure (with motor at minimum displacement)
until maximum displacement is reached is less than 10 bar [145 psi].
This ensures optimal power utilization throughout the entire displacement range of the
motor.
PCOR start pressure is adjustable from 130 to 370 bar [1890 to 5370 psi].

Displacement can be changed
electrohydraulically under load in
response to an electrical signal from
minimum displacement to maximum
displacement and vice versa. The
displacement changes proportional to
the electrical signal. The electrical signal
must be a pulse-width modulated (PWM)
signal, (f = 100...200 Hz). Solenoid not energized = maximum

Pressure Compensator Override (PCOR)
The control can be overridden by PCOR using high loop pressure.
When the PCOR activates, the motor displacement increases to maximum. Pressure
ramp from PCOR start pressure (with motor at minimum displacement) until maximum
displacement is reached is less than 10 bar [145 psi]. This ensures optimal power
utilization throughout the entire displacement range of the motor.
PCOR start pressure is adjustable from 130 to 370 bar [1890 to 5370 psi].
Pressure Compensator Configuration: D7M1, D8M1 with Hydraulic Brake Pressure
Defeat
A shuttle valve ahead of the pressure compensator prevents operation in the
deceleration direction (when motor is running in pump mode). This is designed to
prevent rapid or uncontrolled deceleration while the vehicle/machine is slowing down.
The shuttle valve must be controlled by a 2-line external signal, based on direction of
motor rotation, based on the following table.
Pressure compensator override with brake pressure defeat is mainly used in systems with
pumps having electric or hydraulic proportional controls or automotive controls.
