1
Intermittent = Short term t < 1 min per incident and not exceeding 2 % of duty cycle based load-life
2

3
Cold start = Short term t < 3 min, p ≤ 50 bar [725 psi], n ≤ 1000 min-1(rpm)
Output Speed
Minimum speed is the lowest output speed. Operating below minimum speed limits the system can be
unstable.
Rated speed is the highest input speed recommended at full power condition. Operating at or below
this speed should yield satisfactory product life.
Maximum speed is the highest operating speed permitted. Exceeding maximum speed reduces product
life and can cause loss of hydrostatic power and braking capacity. Never exceed the maximum speed
limit under any operating conditions.
Cleanliness per ISO 4406 22/18/13
Efficiency (charge pressure filtration) β-ratio β15-20 = 75 (β10 ≥ 10)
Efficiency (suction and return line filtration) β35-45 = 75 (β10 ≥ 2)
Recommended inlet screen mesh size µm 100 – 125
System Pressure
Maximum working pressure is the highest recommended application pressure; and it is not intended to
be a continuous pressure. Propel systems with application pressures at, or below, this pressure should
yield satisfactory unit life given proper component sizing.
Maximum pressure is the highest allowable application pressure under any circumstance. Application
pressures above maximum working pressure will only be considered with duty cycle analysis and factory
approval.
Minimum pressure must be maintained under all operating conditions to avoid cavitation.
Case Pressure
Under normal operating conditions, the rated case pressure must not be exceeded. During cold start,
case pressure must be kept below maximum intermittent case pressure.
External Shaft Seal Pressure
In certain applications, the input shaft seal may be exposed to external pressures.
The shaft seal is designed to withstand an external pressure up to 0.4 bar [5.8 psi] above the case
pressure.
The case pressure limits must also be followed to ensure the shaft seal is not damaged.
Temperature
High temperature limits apply at the inlet port of the motor. The motor should run at or below the
maximum continuous temperature.
Cold oil generally does not affect the durability of motor components. It may affect the ability of oil to
flow and transmit power. For this reason, keep the temperature at 16°C
[60 °F] above the pour point of the hydraulic fluid.
Minimum (cold start) temperature relates to the physical properties of component materials.
Maximum continuous temperature is the allowed temperature at which normal life can be expected.

Technical Specifications
Peak (intermittent) temperature: the overheating temperature that is tolerable by the machine for a
transient/limited time.
Viscosity
Minimum viscosity occurs only during brief occasions of maximum ambient temperature and severe
duty cycle operation. It's the minimum acceptable viscosity to allow normal motor life.
Maximum viscosity occurs only during cold start at very low ambient temperatures. It's the upper limit
of viscosity that allows the motor to start.
Temperature and viscosity requirements must be concurrently satisfied. Use petroleum/mineral-based
fluids.
Filtration
To prevent premature wear, ensure only clean fluid enters 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.
These cleanliness levels can not be applied for hydraulic fluid residing in the component housing/case or
any other cavity after transport.
Filtration strategies for TMP include only suction filtration. 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 can 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.
Because each system is unique, only a thorough testing and evaluation program can fully validate the
filtration system. Please see Design Guidelines for Hydraulic Fluid Cleanliness Technical Information,
520L0467 for more information.
1
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 microns) upstream of the filter to the number of
these particles downstream of the filter.
Case Drain
All TM pumps and motors are equipped with two case drain ports. Port selection and case drain routing
must enable the pump housing to maintain a volume of oil not less than half full and normal operating
case pressure limits of the unit are maintained. Case drain routing and design must consider unit case
pressure ratings.
A case drain line must be connected to one of the case outlets to return internal leakage to the system
reservoir.
Reservoir
The reservoir provides clean fluid, dissipates heat, removes entrained air, and allows for fluid volume
changes associated with fluid expansion during system operation. A correctly sized reservoir also
accommodates maximum volume changes during all system operating modes. It promotes de-aeration

Technical Specifications
of the fluid as it passes through, and accommodates a fluid dwell-time between 60 and 180 seconds,
allowing entrained air to escape.
Minimum reservoir capacity depends on the volume required to cool and hold the oil, allowing for
expansion due to temperature changes. A fluid volume of one to three times the motor output flow (per
minute) is satisfactory. The minimum recommended reservoir capacity is 125% of the fluid volume.
Put the return-line below the lowest expected fluid level to allow discharge into the reservoir for
maximum dwell and efficient de-aeration. A baffle (or baffles) between the return and suction lines
promotes de-aeration and reduces fluid surges.

High-pressure relief valve (HPRV)
The TM motors are optionally equipped with a combination of high-pressure relief and check valve. The
high-pressure relief function is a dissipative pressure control valve for the purpose of limiting excessive
system pressures. Each side of the transmission loop has a dedicated HPRV valve that is non-adjustable
with a factory set pressure.
When system pressure exceeds the factory setting of the valve, oil is passed from the high pressure
system loop into the low pressure system loop via the check valve.

Loop flushing shuttle spool
Loop flushing relief valve
An integral loop flushing shuttle spool is used to separate system A and system B pressures, see the
schematic below.
System delta pressure will cause the shuttle spool to shift, allowing the low side system pressure to flow
to the loop flushing relief valve.

Schematic
The loop flushing relief valve is incorporated into all TMM motors. Use the loop flushing option in
Installations that require fluid to be removed from the low pressure side of the system circuit due to
cooling requirements and also used to facilitate the removal of contaminants from the loop.

Speed sensor description
Speed and temperature sensor
Function of the speed sensor is to detect the shaft speed and the direction of rotation.Typically the
sensor will be mounted to the housing of a Danfoss pump or motor and senses the speed from a target
ring that is rotating inside the pump or pistons in cylinder block in motor. Because of the digital output
signals for speed and direction and a non speed dependent output voltage level, the sensor is ideal for
high and low speed measurements.
For diagnostics and other purposes, the sensor also has the capability to detect the case oil temperature.
The speed sensor is designed for rugged outdoor, mobile or heavy industrial speed sensing applications.
The detection of the speed is contactless. It is custom-designed for Danfoss. It is a “plug and perform”
device that does not need any calibration or adjustments.

External radial shaft loads
TM motors are designed with bearings that can accept some external radial and axial loads.
The external radial shaft load limits are a function of the load position and orientation, and the operating
conditions of the unit. The maximum allowable radial load (Re) is based on the maximum external
moment (Me) and the distance (L) from the mounting flange to the load. In applications with external
radial shaft loads, minimize the impact by positioning the load at 0° or 180° as shown in the figure below.
The external radial and axial shaft load are limited by the bearing life L20 =10 000 [h], delta system
pressure 240 bar, speed 1800 min-1 and external radial load at 270°.
It may be determined using the following table and formula below.

The specified torque rating of the shaft documented above is based on the cross-sectional diameter of
the shaft, through the keyway, and assumes the proper clamp and fit between shaft and coupling.
Danfoss guarantees the design and manufactured quality of the splined shaft. The customer is
responsible for the design and manufactured quality of the mating female coupling and key and applied
torque on the nut.
Danfoss has made provisions for the key in accordance to the ISO specification with the understanding
that the key is solely to assist in the installation of the mating coupling.
Warning
Torque or loading inadvertently transmitted by the customer supplied key may lead to premature shaft
failure.
