2 Safety instructions
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.

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.

M10 thread + cut-in
Checking the installed direction of slider
After the installation, the front end of the slider
with M 10 thread and cut-in is located at the
opposite side of the stator from the cable exit.
Slider back end should not be used for
load mounting!
Mounting the stator
The motor is levelled and fixed to the ground using the holes in the flange foot.
The hole pattern is shown in section 9.1 "Stator Dimensions".
Mounting the payload to the slider
The load is mounted as a fixed bearing using spherical washers and conical seats (see the section 6.3).
•To avoid shear force on slider and wear on stator, the payload has to be beared by a
linear guide.
•Slider back end (M8 internal thread) should not be used for load mounting.

"Moving slider" installation
In a "moving slider" installation, the stator is fixed and the slider is the moving part.
The load, borne by a linear guide, is attached directly to the end of the slider. In order to compensate for
misalignment, spherical axial bearings consisting of spherical washers and conical seats (see the section
Slider mounting kits) are used to connect to the load. The mounting kit of slider and an oversized hole for the
screw make it possible to adjust a radial and angle offset.
Mounted payload with radial and angle offset.
"Moving stator" installation
In "moving stator" applications, the slider is fixed and the stator is the moving part.
The load is attached to the stator, which is mounted on a linear guide. In order to avoid an overconstrained
bearing mount and compensate for alignment errors, the slider may be mounted on one end in a fixed
bearing with a spherical axial bearing. On the opposite end, the slider is mounted in a floating bearing.
Mounting kits are available for mounting the slider (see the section Slider mounting kits).

Minimum distance from slider
3.7.1 Minimum distance from slider to slider
The sliders are made of neodymium magnets and have a strong magnetic attraction.
It must be kept a minimum distance between the sliders. This minimized the risk of bruising and secondly,
the sliders do not influence each other through their magnetic fields.

3.7.2 Minimum distance from slider to metallic parts
When installing linear motors in modules with metal parts near the slider, undesired forces can arise due to
magnetic attraction or eddy currents. These generally manifest as erratic and jerky positioning, or reduced
dynamics of the linear motor. In order to avoid this, minimum distances between the slider and any metal
parts are to be observed whenever metal materials are used nearby.

4 Fluid cooling
The heat produced by the motor is dissipated by the liquid cooling. If the motor is operated with a liquid-
cooling, the continuous force value increases many times in comparison with the self-cooling.
Design of water cooling
T_Flow Flow temperature
T_Back Return temperature
∆T T_Back-T_Flow
T_Water Mean coolant temperature, Formula: (T_Flow + T_Back) / 2
Q_Water Flow
∆p Differential pressure
With the water cooling, the coolant is passed through the cooling circuit of the motor flange.
Starting from the adjusted mean coolant temperature T_Water all other parameters of the cooling circuit may
be dimensioned based on the diagrams referred to:
•T_Water -> Pv_Max -> Q_Water ->  p
The design is illustrated by an example in the following.
4.1.1 Determination of the max. possible amount of cont. power dissipation Pv_Max

•If the temperature of the cooling liquid is chosen to be lower than the ambient
temperature, there is a risk of condensation.
•When used and stored in a frost-prone area, corrosion protection (e.g. Clariant) has to
be added.
4.1.2 Determination of water flow Q
Example
•Pv: 450 W
•∆T_Water: 4 °C
-> Q_Water: 1.6 l / min
To achieve a very regular cooling of the motor, the max. difference between flow and return
temperature should not exceed 10 ° C.

Installation Guide Linear Motors ENG
Page 16 / 32 P10-70-SSC / P10-70-SSC-D02 NTI AG / LinMot
4.1.3 Determination of water pressure  p
Example
•Q_Water: 1.6 l / min
-> ∆p: 2 bar
The required water pressure to inject the required water flow depends on the hydraulic resistance of the
cooling circuit.
Corrosion protection
It is advised to add a corrosion protection into the cooling medium (water). A suitable agent can be, for
example, Protectogen C Aqua by Clariant. Information of the mixing ratio between the cooling medium and
the corrosion protection agent can be taken from the manufacturer's instructions.
•Mixing of various corrosion protection agents is to be avoided.
•Corrosion protection products must be matched to the materials of the cooling circuit
(see table of materials in the cooling circuit).
Mounting
The supply or conduction of the cooling medium to the stator is carried out via two connecting thread (see
illustration above). The connection can be realized by M5 push-in fittings.

Attaching the cable shielding
The power cable is supplied with a copper shielding (see illustration above). This prevents electrical and / or
magnetic fields. The shielded part of the cable must be grounded via a connection to the back wall of the
switchboard. The shielding has to be mounted holohedral to the connection part (see scheme above). The
shield connection terminal block is offered as an accessory for power cables and must be ordered separately
(Item-No. 0150-3631) However, the kind of attaching the cable shielding generally depends on the system of
the switchboard manufacturer.
Connectors
For a complete encapsulation the standard motor connector is welded to the housing of the stator. The
connector is designed for tightening and vertically aligned (see the section „Stator dimensions“).
Motor connector and cable connector are firmly bolted together. Dimensions and tightening torque are
shown in the following figure.
