2 Safety instructions
2.1 Appropriate application
The linear motors of the types described here are used exclusively to carry out linear movements. The direct
drives are intended for use in industrial plants. The motors are only operated with original LinMot servo
drives. For external temperature monitoring, 2 temperature sensors and a temperature relay are used, which
interrupts the power supply in the event of a fault. The motors are intended for use in potentially explosive
atmospheres which occasionally occur (zone classification 1, 21, 2, 22 according to DIN EN 60079-14).
Explosivity can consist of gases, vapours, mists and dust. The motors are dimensioned for an ambient
temperature of 0 °C to 50 °C. The motors are designed for a temperature range of 0 °C to 50 °C. The user
determines the operating conditions and thus the maximum surface temperature of the device by means of
the specific type of application of the motors. This allows several temperature classes to be assigned. The
ATEX motors used here correspond to temperature class T4 (max. surface temperature = 135 °C) and T6
(max. surface temperature = 85 °C) according to DIN EN 60079-14. According to this, the devices may be
used in an explosive atmosphere in which the ignition temperature is above the max. surface temperature.

2.2 Warning signs
Contusions
Sliders contain neodynium magnets and have a strong attractive force.
Careless handling could cause fingers or skin to become pinched between two sliders.
This may lead to contusions, bruises, and bone fractures.
When handling sliders, wear thick protective gloves and keep a minimum distance between
sliders. Refer to the "Minimum distance from slider" section for minimum distance.
To reduce the risk of injury, never more than one slider should be held or transported by the
same person without packaging.
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 the following minimum distances between the
pacemaker / defibrillator and slider:
- Min. 250 mm (10ʺ) for slider Ø 27 mm and 28 mm (PL01-27 / 28 / PL10-28)
- Min. 150 mm (6ʺ) for slider Ø 19 mm and 20 mm (PL01-19 / 20)
- Min. 100 mm (4ʺ) for slider Ø 12 mm (PL01-12)
•Inform others who wear these devices to comply with these minimum distances!
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.

Installation Guide Linear Motors ENG
NTI AG / LinMot P01-48 EX protected Page 7 / 40
Combustibility
When machining magnets, the drilling dust could easily ignite.
Machining the sliders and the magnets they contain is not permitted.
Burn hazard
The sliders of LinMot 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.
Mechanical handling
Neodymium magnets are brittle and heat-sensitive.
Machining the sliders and the magnets they contain is not permitted.
•Colliding magnets could crack. Sharp splinters could be catapulted for several meters
and cause eye injury.
•By machining the sliders, heat would result which demagnetises the magnets.
Slider
Linear motor sliders consist of a high-precision, thin-walled stainless steel tube in which the
neodymium magnets are housed. The LinMot sliders should be handled with care.
Avoid contact with other sliders or iron parts as this can damage the magnets and the slider
surface. Do not grip the sliders with pliers, as this can also damage the surface. Do not use
sliders which are already damaged on the surface (scratches, deformation, etc.). This can
cause further damage to the stator.
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 slider away from unshielded flame or heat.
Temperature above 120°C will cause demagnetization.

2.3 Additional ATEX safety instructions
Assembly, commissioning, and maintenance of the motors may be performed only by
qualified personnel who are familiar with the directives of DIN EN 60079-14.
Maintenance and service work may be performed only in a clean room with no explosive
atmosphere. Dangerous ignition sources may arise when disassembling component parts.
Only original parts from LinMot may be used for commissioning and maintenance work.
Always make sure that the external ground connection on the motor
is connected to the PE of the machine.
Do not separate when energized.
Operation is allowed only in conjunction with a temperature relay and line protection.
Only for use with an inverter.
The permissible ambient temperature range is 0°C … +50°C.

LinMot ATEX linear motors are assembled into a complete servo drive system consisting of several
connected components (see the illustration below).

Pos. 5: Power
3.1.1 Circuit breaker
Interrupts the system power supply if the maximum surface temperature setting is exceeded.
3.1.2 LinMot Servo Drive
Performs position control, temperature monitoring, current regulation, and monitoring of the power supply.
3.1.3 Temperature relay
Receives values from the Kty temperature sensors mounted on the exterior of the motor under the stainless
steel housing. In case of a fault (overtemperature), it initiates the interruption of the power supply to the
servo drive. Feedback to the machine control system.
3.1.4 Linear Motor
LinMot motors are direct-drive electromagnetic tubular linear motors.
The main components of the motor are the stator and the slider. The slider, the so-called "magnet bar",
consists of permanent magnets that are arranged with alternating polarization. The stator contains the
windings and position sensors. The windings are fed with current at an appropriate electrical phase angle,
like a permanently excited synchronous motor, thus producing a force in the desired direction. The motor has
3 (or 4) temperature sensors on the windings. These sensors can be used with a series x1100 or x1200
LinMot drive to read and analyze the absolute temperature. This makes it possible to determine the winding

temperature and to shut off the motor in case of a fault. If the drive can no longer communicate with the
motor, then it will shift to a fault state. Feedback is provided to the control system.
The position is sensed by measuring the magnetic field of the slider.
The stator is encapsulated and welded completely shut.
ATEX linear motors can be equipped with a copper cooling system as an option.

Using the manfucturer's "LinMot Designer" software (download from the link
https://linmot.com/download/linmot-designer/), the key data corresponding to the required load situation,
such as peak force, nominal force, or maximum speed, can be calculated and presented.
3.6 Thermal behavior
The motors are equipped with an external temperature monitoring by means of 2 Kty temperature sensors,
which interrupts the power supply when the defined max. surface temperature is exceeded. The table below
must be consulted for setting the temperature relay.
