2 Safety Instructions
Pacemaker / Implanted Heart Defibrillator
Sliders could affect the functioning of pacemakers and implanted heart defibrillators. For the
duration of a strong approach to a magnetic field, these devices switch into test mode and
will not function properly.
•If you wear one of those devices keep a minimum distance of 300 mm (12ʺ) between
the pacemaker / defibrillator and the housing of the linear rotary motor.
•Inform others who wear these devices to comply with this minimum distance!
Caution - Risk of Electric Shock !
Before working, make sure that there are no high voltages.
Fast-moving Machine Parts
The sliders of LinMot linear motors are fast-moving machine parts. All necessary
precautions must be taken to prevent persons approaching the moving elements during
operation (provide covers, guards, etc.).
Automatic Restart
The motors can start automatically under certain cricumstances!
If necessary, a corresponding warning symbol must be provided and protection against
entering the hazardous area or a suitable safe electronic disconnection must be provided!
Risk of Injury due to a Defect or Fault
For areas where a defect or fault can result in substantial property damage or even serious
personal injury, additional external precautions must be taken or devices must be installed
to ensure safe operation even if a defect or fault occurs (eg. suitable safe electronic
disconnection, mechanical interlocks, barriers, etc.).
Magnetic Field
Magnets integrated in the sliders produce a strong magnetic field. They could damage TVs,
laptops, computer hard drives, credit and ATM cards, data storage media, mechanical
watches, hearing aids, and speakers.
•Keep magnets away from devices and objects that could be damaged by strong
magnetic fields.
•For the above mentioned objects, keep a minimum distance as described in the
"Pacemaker / implanted defibrillator" section.
•For non-anti-magnetic watches, keep the double minimum distance.
Burn Hazard
The shaft of LinMot linear rotary motors can reach temperatures of 80 °C, which may cause
burns upon contact.
Grounding
All metal parts that are exposed to contact during any user operation or servicing and likely
to become energized shall be reliably connected to the means for grounding.

Installation Guide Linear Rotary Motors ENG
NTI AG / LinMot PR02-52 Page 7 / 48
Effects on People
According to the current level of knowledge, magnetic fields of permanent magnets do not
have a measurable positive or negative effect on people. It is unlikely that permanent
magnets constitute a health risk, but it cannot be ruled out entirely.
•For your own safety, avoid constant contact with magnets.
•Store large magnets at least one meter away from your body.
Temperature Resistance
Keep motors away from unshielded flame or heat.
Temperature above 120°C will cause demagnetization.

This features a high-precision and complex mechanical system. The optimization of the internal moving load
mass, as well as the moment of inertia, enables a dynamic movement of linear and rotating motion.
The PR02 linear rotary motor is designed for the simultaneous execution of linear and rotating movements.
This means that the rotary and linear movements can be executed simultaneously and completely
independently of each other. However, if the application permits, it is recommended to execute the rotary
movement with the linear rotary shaft retracted, if possible. The rotary and linear movements should also be
carried out one after the other. This reduces the bearing loads and achieves a longer service life of the linear
rotary shaft.
By combining linear and rotary motion, highly complex motion patterns, such as those required in sealing
and assembly applications, can be easily realized using LinMot linear rotary motors. In addition to the two
motors, further options such as an air feed-through, a magnetic spring "MagSpring", a torque sensor and a
force sensor can be integrated in the housing.
3.3 Internal Mechanical Stops
Do not drive into the internal mechanical stops!
It must be ensured that the linear motor does not move to the lower or upper internal stop
during operation, as otherwise the linear motor may be damaged! The internal stops may
only be used for homing purposes. The homing speed must not exceed the value of 0.01
m/s.
3.4 Max. Speed
The mechanically maximum permissible speed of 1500 rpm must not be exceeded.
3.5 Option Load Compensation MagSpring®
The MagSpring option is a passive load compensation based on a magnetic spring with constant force over
the functional stroke range that can be integrated into the module. MagSprings are available in various force
levels and can either push or pull the linear rotary shaft. The MagSpring option can be used to compensate
the load mass. With the correct design, the motor current and thus its power loss can be reduced, by using a
MagSpring. This makes higher cycle rates possible.
If the MagSpring is sized properly, it can move the linear rotary shaft including the load mass into a collision-
free zone in the event of current loss.
•Close to the stroke limit (idle state), the MagSpring has a reduced force to protect the
linear rotary motor from mechanical shocks in case of malfunction/control (self-
acceleration into mechanical stop).
•If the maximum defined stroke (see data sheet) is exceeded, the MagSpring function
can no longer be guaranteed.
3.6 Option Hollow Shaft
Linear rotary motors can optionally be equipped with a pneumatic connection. This allows pneumatic
compressed air or vacuum to be fed directly through the linear rotary shaft. This avoids the complex passage
of hoses around the linear rotary shaft. This option can be used, for example, to control pneumatic grippers
or to pick up parts with the help of vacuum. For more information, see chapter 4.4 Connecting the air.
•In the case of a vacuum application, it is recommended to use a unit with sufficient
power, as any air coupling points are known to produce minor losses.
•Hollow shafts are not intended for the passage of liquid media.
3.7 Option Torque Sensor
The optional, integrated torque sensor enables closed-loop torque control with target torque specification.
The measurement signal is also available to the user for the cyclical recording / evaluation of sensitive
process data (e.g. tightening torque). This enables highly accurate, reproducible and recordable closing and
assembly processes in accordance with Industry 4.0 requirements with an accuracy of <1%.
Torque sensors are based on the measuring principle of strain gauges and transmit the measuring signal
and the supply voltage without contact. This enables low-wear and maintenance-free continuous operation.

Installation Guide Linear Rotary Motors ENG
Page 10 / 48 PR02-52 NTI AG / LinMot
With this option, a suitable, galvanically isolated measuring amplifier is automatically integrated in the linear
rotary motor and provides a measuring signal of +-10 VDC suitable for the LinMot drive.
Factory calibrations of integrated torque sensors are always carried out in the installed state. This has the
advantage that the influences of the mechanics and the linear rotary motor are included.
•The torque measuring shaft is used to measure static as well as dynamic torques. The
sensor can measure both right-hand and left-hand loads. The measured variable is
suitable for control, regulation and monitoring tasks.
•Torque peaks exceeding the permissible overload (see specifications in the PR02 data
sheet) can lead to destruction of the torque measuring shaft. Where such peaks cannot
be safely excluded, they must be mitigated.
•When changing between right and left load, the torque sensor shows a small hysteresis.
•Simultaneously turning and measuring the force can falsify the measurement (e.g. due
to increased friction of the linear rotary shaft).
•The operating temperature range of the sensors is 5 - 45 °C. Above or below the limits,
there is a measurement error which influences the measurement results. It is
recommended to set the offset to zero before each measurement.
•The max. operating range is between 0 - 80 °C.
•For continuously precise measuring results, it is recommended to calibrate the torque
measuring shaft annually according to section 8.3.
•Recalibration is also strongly recommended after improper handling of the force
sensors (e.g. impacts on the linear rotary shaft or large overloads).
3.8 Option Force Sensor
The optional force sensor enables closed-loop force control with target force specification. The measurement
signal is also available to the user for the cyclical recording / evaluation of sensitive process data (e.g.
bounce force). This makes it easy to implement highly accurate, reproducible and recordable pressing and
assembly processes in accordance with Industry 4.0 requirements with an accuracy of <1%.
Force sensors are based on the measuring principle of strain gauges. They are designed to withstand
multiple mechanical overloads and still precisely detect the smallest forces. With this option, a suitable,
galvanically isolated measuring amplifier is automatically integrated in the linear rotary motor and provides a
measuring signal of +-10 VDC suitable for the LinMot drive.
Factory calibrations of integrated force sensors are always carried out in the installed state. This has the
advantage that the influences of the mechanics and the linear rotary motor are included.
•The force sensor is used to measure compressive and tensile forces. The measured
variable is suitable for control, regulation and monitoring tasks.
•Force peaks exceeding the permissible overload (see information in the PR02 data
sheet) can lead to destruction of the force sensor. Where such peaks cannot be safely
excluded, they must be mitigated.
•When changing between increasing and decreasing forces, the force sensor shows a
small hysteresis.
•Due to the static friction in the system, the force sensor measures more accurately if the
force vector always points in the same direction during repeated measurement
(influence of force hysteresis).
•To increase the measuring accuracy, linear rotary motors with integrated force sensor
technology are supplied without sealing lips / wipers.
•Simultaneous rotation and measurement of the force can falsify the measurement (e.g.
due to increased friction of the linear rotary shaft).
•The operating temperature range of the sensors is 5 - 45 °C. Above or below the limits,
there is a measurement error which influences the measurement results. It is
recommended to set the offset to zero before each measuring process.
•The max. operating range is between 0 - 80 °C.
•For continuously precise measurement results, it is recommended to calibrate the force
sensor annually according to section 8.3.
•Recalibration is also strongly recommended after improper handling of the force
sensors (e.g. impacts on the stroke rotating shaft or large overload).

NTI AG / LinMot PR02-52 Page 11 / 48
3.9 Option Stainless Steel Front Flange (SSC)
The stainless steel front flange option offers the user hygiene at the highest level. Linear rotary motors with
this option can be used in machines and systems for processing food products or in the pharmaceutical and
medical industries. With this option, the user benefits from a partially increased IP degree of protection as
well as the possibility to use the front of the linear rotary motor even in extremely rough or corrosive
environments where aggressive cleaning agents are used.
•The exact list of materials used can be found in chapter 4.6.
•The user is obliged to check whether the cleaning agents used are compatible with the
materials of the stainless steel front flange.
•The stainless steel front flange may only be cleaned when the axle is at a standstill. It is
recommended that cleaning is carried out with the linear rotary shaft extended.
The linear rotary shaft must be dried before it is put back into operation.
•Any parts that do not belong to the zone of the stainless steel front flange may not be
corrosion-resistant and can therefore only be cleaned to a limited extent. They have a
reduced IP degree of protection.
•The specified IP degree of protection is achieved at standstill.
3.10 Option Stainless Steel Housing (SSCH)
The SSCH housing option extends the SSC front option and encases the entire reciprocating rotary motor
with a stainless steel housing. As a result, such motors have a uniformly high IP protection rating (IP69s) and
can withstand "in place" cleaning processes such as CIP and SIP. They are specially designed for the food
or pharmaceutical & medical industry.
3.11 Option Pneumatic Holding Brake
Linear rotary motors are electromagnetic direct drives and therefore do not have self-locking. In order to fix
the linear rotary shaft in the de-energized state, the pneumatic holding brake option can also be used as an
alternative to the MagSpring option.
The pneumatic holding brake is a one-way cylinder with spring return, which can be mounted on the front of
the PR02-52 motor. To open and close the brake, an additional electric solenoid valve is required which is
controlled by the LinMot Servo Drive. The spring return is released by compressed air and guarantees the
braked state even in the event of a pressure drop.
To reduce wear, it is recommended to control the brake via the LinMot Drive.
•The brake has a pure holding function and is not designed to slow down or stop
dynamic movements.
•Not to be used for safety devices!
•Not approved as a safety element!
3.12 Option angled Motor Connector (R01)
In order to offer the user an even shorter installation length, linear rotary motors of the PR02-52 family are
optionally available with a motor angle connector. Since this option is only a mechanical variant, the function
of the motor remains the same.
•Further information can be found in the drawings in chapter 10.
•PR02-52 linear rotary motors with the angled motor connector are only available on
request.

4 Installation Instructions
4.1 Operating Conditions
Maximum ambient temperature limits:
•-10 °C…80 °C
Internal temperature sensor error occurs at:
•90 °C
Max. installation altitude
•The max. installation altitude is 4'000 m above sea level.
From 1'000 m, derating of 1 °C per 100 m is to be considered for air cooling.
4.2 Installation Options
The PR02 linear motors have a centric fit (technical data in the chapter "Dimensions") on the front so that an
exact alignment of the rotary axis is possible.
Mounting only via the front screws is generally not sufficient (vibrations, transverse load) and must be
supplemented by another support. For reasons of vibration, a support as far back as possible is preferable.
See the installation examples in the following chapter. To ensure that the motor is not installed in the
machine with tension, tolerance compensation (see next chapter) must be provided. The detailed mounting
dimensions can be found in chapter 10 "Dimensions". The corresponding CAD files are available in the
LinMot eCatalogue https://shop.linmot.com/
4.2.1 Horizontal Installation
The PR02 linear rotary motor can be mounted horizontally using the
T-slots at the bottom.
T-nuts (M4 / M5 / M6) can be used for fastening.

4.2.2 Vertical Installation
The T-slots on the underside of the PR02 are used for stable
vertical mounting (see explanation above). In addition, the front of
the motor should be fixed using the 4 tapped holes. The positions of
the tapped holes can be found in the "Dimensions" section.
In order to avoid overdetermination of the different
motor bearings, the support must have a minimum
clearance. This compensates for any tolerances in the
linear rotary motor.
4.3 Mounting the Load on the Shaft
The assembly and disassembly of the load mass must not take place in the mechanical end
stops of the linear movement. An external support must be used.
4.3.1 Feather Key
The load mass is mounted either by means of a feather key or a shaft-hub clamping.
For the first mounting variant, a feather key slot is incorporated at the end of the shaft.

4.3.2 Shaft-Hub Clamping
The shaft-hub clamping is a non-positive
connection which is produced by means of two
conical rings.
The use of drivers or the production of grooves is
completely eliminated. The suitable shaft-hub
clamping type can be ordered from LinMot.
Mounting instructions and ordering information can
be found in the "Accessories" chapter.
4.4 Connection of Air
The PR02-52 is optionally equipped with an air connection. At the rear of the motor, above the electrical
connectors, there is a pneumatic push-in fitting (external hexagon M5) for a Ø 4 mm hose. Inside the motor,
a Ø 4 mm air hose is laid along the rotating shaft, which has a continuous hole diameter of Ø 2.5 mm.
This enables the user to implement pneumatic applications with an operating pressure of max. 6 bar.
In the case of vacuum application, it is recommended to use a unit with sufficient power, as experience has
shown that all air coupling points generate small losses.

Bridges from Supply Ground and Signal Ground
•PIN 4 (force -) and PIN 1 (supply GND) are internally galvanically isolated and must not
be connected to each other. This applies to sensors with a 10-digit serial number.
Format = 0123.456.789.
•For torque sensors with 9-digit serial number (format = 123456789) PIN 4 (torque -) and
PIN 1 (supply GND) may be bridged at the supply source (not at the transducer), if
necessary, because the galvanic isolation is not present there. Make the connection as
close as possible to the drive to avoid potential differences with respect to the drive
GND
•The 24VDC supply must be protected with a 1AT fuse.
•The +24V supply must not be connected / disconnected when voltage is present. The
DC supply must not be switched on the secondary side of the power supply unit.
•It is recommended to connect pin 6 (AGND) to the reference ground of the analogue
input of the drive - in case of LinMot drives pin X4.1. realise connection as close to the
drive as possible to avoid potential differences compared to the drive GND.
•External EMC circuitry: a ceramic capacitor 100nF / 50V can optionally be soldered
between pin 4 and pin 5 on the evaluation electronics to reduce conducted interference.

6 Start-up
Please note that linear rotary motors of the PR02 product family need at least LinMot-Talk
Version 6.7. It’s not recommended to use older LinMot-Talk versions.
6.1 Linear Motor and Rotary Motor
Linear motor and rotary motor are electrically independent units. The linear rotary motor can therefore be
commissioned sequentially. It does not matter which motor (linear motor or rotary motor) is commissioned
first.
The various parameters for the linear motor and the rotary motor are set on the drive side using the
corresponding wizard in the LinMot Talk configuration program.
Do not drive into the internal mechanical stops!
It must always be ensured that the linear motor never moves into the lower or upper internal
stop during operation, as otherwise the linear rotary motor and the force sensor may be
damaged! The inner stops may be used for homing purposes; the homing speed must not
exceed 0.01 m/s.
6.2 Default Values of the Coordinate System
6.2.1 Angle of Rotation
Looking into the shaft, the counterclockwise
counting direction of the rotation angle is defined as
positive.
6.2.2 Position
With regard to the motor, the positive counting
direction of the position is defined by retracting the
linear rotary shaft.

6.3 Torque Measuring Shaft
Linear rotary motors of the LinMot PR02 motor family can optionally have a torque
measuring shaft built into the module. Please make sure that the option „Torque measuring
shaft“ is selected during the ordering process. Fitting of the torque measuring shaft
afterwards is not possible.
6.3.1 Torque Operating Direction
Looking into the shaft, the anti-clockwise direction is defined as
positive.
6.4 Force Sensor
Linear rotary motors of the LinMot PR02 motor family can optionally have a force sensor
built into the module. Please make sure that the option „Force sensor“ is selected during the
ordering process. Fitting of force sensor afterwards is not possible.
6.4.1 Force Operating Direction
101 mm
Looking to the motor, the positive stroke (force)
direction is defined by retracting the linear rotary
shaft.
The direction of stroke can be changed from LinMot-Talk version 6.8 onwards. This has an
influence on the parameterization of the force sensor as the positive force direction will
change as well.
+
The direction of rotation can be changed from LinMot-Talk version 6.8 onwards. This has an
influence on the parameterization of the torque measuring shaft.
