OPERATING RECOMMENDATIONS
OIL TYPE
Hydraulic oils with anti-wear, anti-foam and demulsiers
are recommended for systems incorporating Danfoss mo­tors. Straight oils can be used but may require VI (viscosity index) improvers depending on the operating temperature range of the system. Other water based and environmen­tally friendly oils may be used, but service life of the motor
and other components in the system may be signicantly shortened. Before using any type of uid, consult the uid
requirements for all components in the system for compat­ibility. Testing under actual operating conditions is the only way to determine if acceptable service life will be achieved.
FLUID VISCOSITY & FILTRATION
Fluids with a viscosity between 20 - 43 cSt [100 - 200 S.U.S.] at operating temperature is recommended. Fluid temperature should also be maintained below 85°C [180° F]. It is also suggested that the type of pump and its oper-
ating specications be taken into account when choosing a uid for the system. Fluids with high viscosity can cause
cavitation at the inlet side of the pump. Systems that operate over a wide range of temperatures may require viscosity
improvers to provide acceptable uid performance.
congured for this condition, damage to the motor or system
can occur. To protect against this condition a counterbal­ance valve or relief cartridge must be incorporated into the
circuit to reduce the risk of overpressurization. If a relief
cartridge is used, it must be installed upline of the motor, if not in the motor, to relieve the pressure created by the over-running motor. To provide proper motor protection for an over-running load application, the pressure setting of the pressure relief valve must not exceed the intermittent rating of the motor.
HYDRAULIC MOTOR SAFETY PRECAUTION
A hydraulic motor must not be used to hold a suspended load. Due to the necessary internal tolerances, all hydraulic motors will experience some degree of creep when a load induced torque is applied to a motor at rest. All applica­tions that require a load to be held must use some form of
mechanical brake designed for that purpose.
MOTOR/BRAKE PRECAUTION
Caution! - Danfoss motor/brakes are intended to operate as
static or parking brakes. System circuitry must be designed to bring the load to a stop before applying the brake.
Danfoss recommends maintaining an oil cleanliness level of ISO 17-14 or better.
INSTALLATION & START-UP
When installing a Danfoss motor it is important that the
mounting ange of the motor makes full contact with the
mounting surface of the application. Mounting hardware of the appropriate grade and size must be used. Hubs, pul-
leys, sprockets and couplings must be properly aligned to
avoid inducing excessive thrust or radial loads. Although
the output device must t the shaft snug, a hammer should
never be used to install any type of output device onto the shaft. The port plugs should only be removed from the mo­tor when the system connections are ready to be made. To avoid contamination, remove all matter from around the
ports of the motor and the threads of the ttings. Once all
system connections are made, it is recommended that the motor be run-in for 15-30 minutes at no load and half speed to remove air from the hydraulic system.
MOTOR PROTECTION
Over-pressurization of a motor is one of the primary causes of motor failure. To prevent these situations, it is necessary to provide adequate relief protection for a motor based on the pressure ratings for that particular model. For systems that may experience overrunning conditions, special pre-
cautions must be taken. In an overrunning condition, the motor functions as a pump and attempts to convert kinetic
energy into hydraulic energy. Unless the system is properly
Caution! - Because it is possible for some large displace-
ment motors to overpower the brake, it is critical that the
maximum system pressure be limited for these applications. Failure to do so could cause serious injury or death. When
choosing a motor/brake for an application, consult the
performance chart for the series and displacement chosen for the application to verify that the maximum operating pressure of the system will not allow the motor to produce
more torque than the maximum rating of the brake. Also,
it is vital that the system relief be set low enough to insure
that the motor is not able to overpower the brake.
To ensure proper operation of the brake, a separate case drain back to tank must be used. Use of the internal drain
option is not recommended due to the possibility of return
line pressure spikes. A simple schematic of a system utiliz­ing a motor/brake is shown on page 4. Although maximum brake release pressure may be used for an application, a
34 bar [500 psi] pressure reducing valve is recommended
to promote maximum life for the brake release piston seals.
However, if a pressure reducing valve is used in a system
which has case drain back pressure, the pressure reducing
valve should be set to 34 bar [500 psi] over the expected
case pressure to ensure full brake release. To achieve proper brake release operation, it is necessary to bleed out any trapped air and ll brake release cavity and hoses
before all connections are tightened. To facilitate this op-
eration, all motor/brakes feature two release ports. One or both of these ports may be used to release the brake in the

unit. Motor/brakes should be congured so that the release
ports are near the top of the unit in the installed position.
MOTOR CIRCUITS
There are two common types of circuits used for connect­ing multiple numbers of motors – series connection and parallel connection.
SERIES CONNECTION
When motors are connected in series, the outlet of one mo­tor is connected to the inlet of the next motor. This allows
the full pump ow to go through each motor and provide
maximum speed. Pressure and torque are distributed be­tween the motors based on the load each motor is subjected to. The maximum system pressure must be no greater than
the maximum inlet pressure of the rst motor. The allowable back pressure rating for a motor must also be considered. In
some series circuits the motors must have an external case drain connected. A series connection is desirable when it is important for all the motors to run the same speed such as on a long line conveyor.
Once all system connections are made, one release port
must be opened to atmosphere and the brake release line carefully charged with uid until all air is removed from the line and motor/brake release cavity. When this has been
accomplished the port plug or secondary release line must be reinstalled. In the event of a pump or battery failure, an
external pressure source may be connected to the brake release port to release the brake, allowing the machine to
be moved.
NOTE: It is vital that all operating recommendations be followed. Failure to do so could result in injury or death.
PARALLEL CONNECTION
In a parallel connection all of the motor inlets are connected.
This makes the maximum system pressure available to
each motor allowing each motor to produce full torque at
that pressure. The pump ow is split between the individual
motors according to their loads and displacements. If one
motor has no load, the oil will take the path of least resis­tance and all the ow will go to that one motor. The others will not turn. If this condition can occur, a ow divider is
recommended to distribute the oil and act as a differential.
NOTE: The motor circuits shown above are for illustration purposes only. Components and circuitry for actual applications may vary greatly and should be chosen based on the application.

-100 -50 -25 0255075 100 mm-75
This catalog provides curves showing allowable radial loads at points along the longitudinal axis of the motor. They are
dimensioned from the mounting ange. Two capacity curves for the shaft and bearings are shown. A vertical line through
the centerline of the load drawn to intersect the x-axis intersects the curves at the load capacity of the shaft and of the bearing.
In the example below the maximum radial load bearing rating is between the internal roller bearings illustrated with a solid line. The allowable shaft rating is shown with a dotted line.
The bearing curves for each model are based on labratory analysis and testing results constructed at Danfoss. The shaft loading is based on a 3:1 safety factor and 330 Kpsi tensile strength. The allowable load is the lower of the curves at a
given point. For instance, one inch in front of the mounting ange the bearing capacity is lower than the shaft capacity.
In this case, the bearing is the limiting load. The motor user needs to determine which series of motor to use based on
their application knowledge.
ISO 281 RATINGS VS. MANUFACTURERS RATINGS
Published bearing curves can come from more than one type of analysis. The ISO 281 bearing rating is an interna-
9000

tional standard for the dynamic load rating of roller bearings. The rating is for a set load at a speed of 33 1/3 RPM for 500 hours (1 million revolutions). The standard was estab­lished to allow consistent comparisons of similar bearings between manufacturers. The ISO 281 bearing ratings are based solely on the physical characteristics of the bear-
ings, removing any manufacturers specic safety factors or empirical data that inuences the ratings.
Manufacturers’ ratings are adjusted by diverse and system-
atic laboratory investigations, checked constantly with feed­back from practical experience. Factors taken into account
that affect bearing life are material, lubrication, cleanliness

VEHICLE DRIVE CALCULATIONS
When selecting a wheel drive motor for a mobile vehicle,
a number of factors concerning the vehicle must be taken
into consideration to determine the required maximum motor RPM, the maximum torque required and the maximum load each motor must support. The following sections contain the necessary equations to determine this criteria. An example is provided to illustrate the process.
Sample application (vehicle design criteria)
vehicle description .....................................4 wheel vehicle
vehicle drive.................................................. 2 wheel drive
GVW .................................................................1,500 lbs.
weight over each drive wheel ................................425 lbs.
rolling radius of tires ..................................................16 in.
desired acceleration .............................0-5 mph in 10 sec.
top speed ................................................................. 5 mph
gradability ................................................................... 20%
worst working surface .....................................poor asphalt
To determine maximum motor speed
RPM =
2.65 x KPH x G rm
RPM =
168 x MPH x G
ri Where: MPH = max. vehicle speed (miles/hr)
KPH = max. vehicle speed (kilometers/hr)
ri = rolling radius of tire (inches) G = gear reduction ratio (if none, G = 1) rm = rolling radius of tire (meters)
Example
RPM = = 52.5
168 x 5 x 1
16
To determine maximum torque requirement of motor
To choose a motor(s) capable of producing enough torque to propel the vehicle, it is necessary to determine the Total Tractive Effort (TE) requirement for the vehicle. To determine the total tractive effort, the following equa­tion must be used:
TE = RR + GR + FA + DP (lbs or N)
Where: TE = Total tractive effort RR = Force necessary to overcome rolling resistance GR = Force required to climb a grade FA = Force required to accelerate DP = Drawbar pull required
The components for this equation may be determined using the following steps:
Step One: Determine Rolling Resistance
Rolling Resistance (RR) is the force necessary to propel a vehicle over a particular surface. It is recommended that the worst possible surface type to be encountered by the vehicle be factored into the equation.
RR = x R (lb or N)
GVW
1000
Where:
GVW = gross (loaded) vehicle weight (lb or kg)
R = surface friction (value from Table 1)
Example
1500
RR = x 22 lbs = 33 lbs

Concrete (good)....................15

Dirt (sandy) ........................... 37
Mud............................37 to 150
Sand (soft) ................. 60 to 150
Sand (dune) ............. 160 to 300
Step Two: Determine Grade Resistance
Grade Resistance (GR) is the amount of force necessary to move a vehicle up a hill or “grade.” This calculation must be made using the maximum grade the vehicle will be expected to climb in normal operation.
To convert incline degrees to % Grade: % Grade = [tan of angle (degrees)] x 100
GR = x GVW (lb or N)

VEHICLE DRIVE CALCULATIONS
Step Three: Determine Acceleration Force
Acceleration Force (FA) is the force necessary to acceler­ate from a stop to maximum speed in a desired time.
MPH x GVW (lb)
FA =
22 x t
KPH x GVW (N)
FA =
35.32 x t
Where: t = time to maximum speed (seconds)
Example FA = = 34 lbs
5 x 1500 lbs
22 x 10
Step Four: Determine Drawbar Pull
Drawbar Pull (DP) is the additional force, if any, the vehicle will be required to generate if it is to be used to tow other equipment. If additional towing capacity is required for the equipment, repeat steps one through three for the towable equipment and sum the totals to determine DP.
Step Five: Determine Total Tractive Effort
The Tractive Effort (TE) is the sum of the forces calcu­lated in steps one through three above. On low speed vehicles, wind resistance can typically be neglected. However, friction in drive components may warrant the addition of 10% to the total tractive effort to insure ac­ceptable vehicle performance.
Step Seven: Determine Wheel Slip
To verify that the vehicle will perform as designed in re­gards to tractive effort and acceleration, it is necessary to calculate wheel slip (TS) for the vehicle. In special cases, wheel slip may actually be desirable to prevent hydraulic
system overheating and component breakage should the
vehicle become stalled.
W x f x ri
TS =
G
(lb-in per motor)
W x f x rm
TS =
G
(N-m per motor)
Where:
f = coefcient of friction (see table 2)
W = loaded vehicle weight over driven wheel (lb or N)
Example TS = lb-in/motor = 4080 lbs
425 x .06 x 16

Steel on steel ........................................ 0.3
Rubber tire on dirt ................................. 0.5
Rubber tire on a hard surface ....... 0.6 - 0.8
Rubber tire on cement .......................... 0.7
TE = RR + GR + FA + DP (lb or N)
Example TE = 33 + 300 + 34 + 0 (lbs) = 367 lbs
Step Six: Determine Motor Torque
The Motor Torque (T) required per motor is the Total Tractive Effort divided by the number of motors used on the machine. Gear reduction is also factored into account in this equation.
TE x ri
T = lb-in per motor
M x G
TE x rm
T = Nm per motor
M x G
Where: M = number of driving motors
Example T = lb-in/motor = 2936 lb-in
367 x 16
2 x 1
To determine radial load capacity requirement of motor
When a motor used to drive a vehicle has the wheel or hub attached directly to the motor shaft, it is critical that
the radial load capabilities of the motor are sufcient
to support the vehicle. After calculating the Total Ra­dial Load (RL) acting on the motors, the result must be compared to the bearing/shaft load charts for the chosen motor to determine if the motor will provide acceptable load capacity and life.
RL = W
Example RL =

Once the maximum motor RPM, maximum torque requirement, and the maximum load each motor must
support have been determined, these gures may then
be compared to the motor performance charts and to the bearing load curves to choose a series and displacement
to fulll the motor requirements for the application.

Side Load = 14855 Nm [3333 lbs]
In many cases, pulleys or sprockets may be used to transmit
the torque produced by the motor. Use of these components will create a torque induced side load on the motor shaft
and bearings. It is important that this load be taken into consideration when choosing a motor with sufcient bearing
and shaft capacity for the application.

To determine the side load, the motor torque and pulley or sprocket radius must be known. Side load may be calcu­lated using the formula below. The distance from the pul-
ley/sprocket centerline to the mounting ange of the motor must also be determined. These two gures may then be
compared to the bearing and shaft load curve of the desired motor to determine if the side load falls within acceptable load ranges.

SPEED SENSORS
Danfoss offers both single and dual element speed sensor options providing a number of benets to users by incorpo­rating the latest advancements in sensing technology and materials. The 700 & 800 series motors single element sen­sors provide 60 pulses per revolution with the dual element providing 120 pulses per revolution, with all other series providing 50 & 100 pulses respectively. Higher resolution
is especially benecial for slow speed applications, where
more information is needed for smooth and accurate control. The dual sensor option also provides a direction signal al­lowing end-users to monitor the direction of shaft rotation .
Unlike competitive designs that breach the high pressure
area of the motor to add the sensor, the Danfoss speed
sensor option utilizes an add-on ange to locate all sensor
components outside the high pressure operating environ-
ment. This eliminates the potential leak point common to
competitive designs. Many improvements were made to
the sensor ange including changing the material from
cast iron to acetal resin, incorporating a Buna-N shaft seal
internal to the ange, and providing a grease zerk, which allows the user to ll the sensor cavity with grease. These improvements enable the ange to withstand the rigors of
harsh environments.
Another important feature of the new sensor ange is that it
is self-centering, which allows it to remain concentric to the magnet rotor. This produces a consistent mounting location for the new sensor module, eliminating the need to adjust
the air gap between the sensor and magnet rotor. The o-
ring sealed sensor module attaches to the sensor ange
with two small screws, allowing the sensor to be serviced
or upgraded in the eld in under one minute. This feature is
especially valuable for mobile applications where machine downtime is costly. The sensor may also be serviced without exposing the hydraulic circuit to the atmosphere. Another
advantage of the self-centering ange is that it allows users
to rotate the sensor to a location best suited to their applica­tion. This feature is not available on competitive designs,
which x the sensor in one location in relationship to the motor mounting ange.
FEATURES / BENEFITS
Grease tting allows sensor cavity to be lled with
• grease for additional protection.
Internal extruder seal protects against environmental
• elements.
M12 or weatherpack connectors provide installation
exibility.
Dual element sensor provides up to 120 pulses per
• revolution and directional sensing.
Modular sensor allows quick and easy servicing.
Acetal resin ange is resistant to moisture, chemi-
• cals, oils, solvents and greases.
Self-centering design eliminates need to set magnet-
• to-sensor air gap.

Unprotected versions are also available for operation at lower voltages down to 4.5V.
FREE TURNING ROTOR
The ‘AC’ option or “Free turning” option refers to a specially prepared rotor assembly. This rotor assembly has increased clearance between the rotor tips and rollers allowing it to turn more freely than a standard rotor assembly. For spool valve motors, additional clearance is also provided between the shaft and housing bore. The ‘AC’ option is available for all motor series and displacements.
There are several applications and duty cycle conditions where ‘AC’ option performance characteristics can be
benecial. In continuous duty applications that require high ow/high rpm operation, the benets are twofold. The ad-
ditional clearance helps to minimize internal pressure drop
at high ows. This clearance also provides a thicker oil lm
at metal to metal contact areas and can help extend the life of the motor in high rpm or even over speed conditions. The ‘AC’ option should be considered for applications that require continuous operation above 57 LPM [15 GPM] and/
or 300 rpm. Applications that are subject to pressure spikes due to frequent reversals or shock loads can also benet
by specifying the ‘AC’ option. The additional clearance
serves to act as a buffer against spikes, allowing them to
be bypassed through the motor rather than being absorbed
and transmitted through the drive link to the output shaft. The trade-off for achieving these benets is a slight loss of volumetric efciency at high pressures.

INTERNAL DRAIN
The internal drain is an option available on all HB, DR, and DT Series motors, and is standard on all WP, WR, WS, and D9 series motors. Typically, a separate drain line
must be installed to direct case leakage of the motor back
to the reservoir when using a HB, DR, or DT Series motor. However, the internal drain option eliminates the need for
a separate drain line through the installation of two check valves in the motor endcover. This simplies plumbing
requirements for the motor.
The two check valves connect the case area of the motor to
each port of the endcover. During normal motor operation, pressure in the input and return lines of the motor close the
check valves. However, when the pressure in the case of the motor is greater than that of the return line, the check
valve between the case and low pressure line opens, al-
lowing the case leakage to ow into the return line. Since the operation of the check valves is dependent upon a
pressure differential, the internal drain option operates in either direction of motor rotation.
Although this option can simplify many motor installations, precautions must be taken to insure that return line pres­sure remains below allowable levels (see table below) to insure proper motor operation and life. If return line pressure
is higher than allowable, or experiences pressure spikes, this pressure may feed back into the motor, possibly caus-
ing catastrophic seal failure. Installing motors with internal drains in series is not recommended unless overall pres­sure drop over all motors is below the maximum allowable
backpressure as listed in the chart below. If in doubt, contact
your authorized Danfoss representative.

HYDRAULIC DECLUTCH
The declutch or ‘AE’ option, available on the RE and CE Series motors, has been specically designed for applica­tions requiring the motor to have the ability to “freewheel”
when not pressurized. By making minor changes to internal
components, the torque required to turn the output shaft is minimal. Selection of this option allows freewheeling speeds up to 1,000 RPM* depending on the displacement of the motor and duty cycle of the application.
To enable the motor to perform this function, the standard rotor assembly is replaced with a freeturn rotor assembly. Next, the standard balance plate and endcover is replaced with a special wear plate and ported endcover. The wear
plate features seven holes that connect the stator pockets
to each other. The ported endcover features a movable piston capable of sealing the seven holes in the wear plate.
When standard motor function is required, pressure is supplied to the endcover port, moving the piston against the wear plate. This action seals the seven holes allowing the motor to function as normal. However, when pressure is removed from the endcover port, the pressure created by the turning rotor assembly pushes the piston away from
the wear plate, opening the rotor pockets to each other. In
this condition, oil may circulate freely within the rotor and endcover assemblies, allowing the rotor assembly to rotate freely within the motor.
This option is especially useful in applications ranging from winch drives to towable wheel drives. Depending on the valves and hydrau­lic circuitry, operation of the freewheel function may be manually or automatically selected. A basic schematic is shown to the right.
The 1,000 RPM rating was based on smaller displacement options with forced ow ushing
through the motor to provide cooling.

VALVE CAVITY
The valve cavity option provides a cost effective way to incorporate a variety of cartridge valves integral to the mo­tor. The valve cavity is a standard 10 series (12 series on the 800 series motor) 2-way cavity that accepts numerous
cartridge valves, including overrunning check valves, relief cartridges, ow control valves, pilot operated check fuses,
and high pressure shuttle valves. Installation of a relief car­tridge into the cavity provides an extra margin of safety for
applications encountering frequent pressure spikes. Relief
cartridges from 69 to 207 bar [1000 to 3000 psi] may also be factory installed.
SLINGER SEAL
Slinger seals are available on select series offered by Danfoss. Slinger seals offer extendes shaft/shaft seal protection by prevented a buildup of material around the circumference of the shaft which can lead to premature shaft seal failures. The Danfoss slinger seals are designed to be larger in diameter than competitive products, providing greater surface speed and ‘slinging action’.
For basic systems with xed displacement pumps, either manual or motorized ow control valves may be installed
into the valve cavity to provide a simple method for con­trolling motor speed. It is also possible to incorporate the speed sensor option and a programmable logic controller
with a motorized ow control valve to create a closed loop,
fully automated speed control system. For motors with
internal brakes, a shuttle valve cartridge may be installed
into the cavity to provide a simple, fully integrated method for supplying release pressure to the pilot line to actuate an
integral brake. To discuss other alternatives for the valve
cavity option, contact an authorized Danfoss distributor.
Slinger seals are also available on 4-hole ange mounts
on select series. Contact a Danfoss Customer Service Representative for additional information.

RE
(All Series)
For Medium Duty Applications
OVERVIEW
RE Series motors offer the perfect compromise between
price and performance by producing work horse power at
a reasonable cost. Although these motors perform well in a wide range of applications, they are especially suited
for low ow, high pressure applications. During startup, pressure causes the balance plate to ex toward the rotor, vastly improving volumetric efciency. As the motor reaches
operating pressure, the balance plate relaxes, allowing the rotor to turn freely which translates into higher mechanical
efciencies. Transmitting this power to the output shaft is the most durable drive link in its class. Four bearing op­tions, combined with standard mounting anges and output shafts, allow the motor to be congured to suit nearly any
application.
FEATURES / BENEFITS
High Pressure Shaft Seal offers superior seal life and performance and eliminates need for case drain.
Three Bearing Options allow load carrying capability of
motor to be matched to application.
Heavy-Duty Drive Link is the most durable in its class
and receives full ow lubrication to provide long life.
Valve-In-Rotor Design provides cost effective, efcient
distribution of oil and reduces overall motor length.
