Safety Regulations
These Safety Regulations are user hints only and may not be complete!
General Guidelines
DANGER Danger of death!
Do not touch voltage-carrying cables and
components.
Clutches may generate further risks, among other things:
Hand
injuries
Danger of
seizure
Contact with
hot
surfaces
Magnetic
fields
Severe injury to people and damage to objects may result if:
 the electromagnetic clutch is used incorrectly.
 the electromagnetic clutch is modified.
 the relevant standards for safety and / or installation
conditions are ignored.
During the required risk assessment when designing the
machine or system, the dangers involved must be evaluated and
removed by taking appropriate protective measures.
To prevent injury or damage, only professionals and
specialists are allowed to work on the devices.
They must be familiar with the dimensioning, transport,
installation, initial operation, maintenance and disposal
according to the relevant standards and regulations.
Before product installation and initial operation,
please read the Installation and Operational
Instructions carefully and observe the Safety
Regulations. Incorrect operation can cause injury
or damage.
The electromagnetic clutches have been developed and
manufactured in accordance with the known technical
specifications and are operationally safe at the time of delivery.
 Technical data and specifications (Type tags and
documentation) must be followed.
 The correct connection voltage must be connected
according to the Type tag and wiring guidelines.
 Check electrical components for signs of damage before
putting them into operation. Never bring them into contact
with water or other fluids.
 Please observe the EN 60204-1 requirements for electrical
connection when using in machines.
Only carry out installation, maintenance and
repairs in a de-energised, released state and
secure the system against inadvertent switch-
on.
Guidelines for Electromagnetic Compatibility
(EMC)
In accordance with the EMC directive 2004/108/EC, the
individual components produce no emissions. However,
functional components e.g. mains-side energisation of the
clutches with rectifiers, phase demodulators, ROBA®-switch
devices or similar controls can produce disturbance which lies
above the allowed limit values.
For this reason it is important to read the Installation and
Operational Instructions very carefully and to keep to the EMC
directives.
Application Conditions
The catalogue values are guideline values which
have been determined in test facilities. It may be
necessary to carry out your own tests for the
intended application. When dimensioning the
clutches, please remember that installation
situations, torque fluctuations, permitted friction work, run-in
behaviour and wear as well as general ambient conditions can
all affect the given values. These factors should therefore be
carefully assessed, and alignments made accordingly.
 Mounting dimensions and connecting dimensions must be
adjusted according to the size of the clutch at the place of
installation.
 The magnetic coils are designed for a relative duty cycle of
100 %.
 The torque is dependent on the present run-in condition of
the clutches.
 The clutches are only designed for dry running. The torque
is lost if the friction surfaces come into contact with oil,
grease, water or similar substances or foreign bodies.
 The surfaces of the outer components have been zinc
phosphated manufacturer-side to form a basic corrosion
protection.
CAUTION The rotors may rust up and block in corrosive
ambient conditions and/or after long periods of
storage.
The user is responsible for taking appropriate
counter measures.

Safety Regulations
These Safety Regulations are user hints only and may not be complete!
Ambient Temperature: – 20 °C up to + 40 °C
CAUTION At temperatures of around or under freezing
point, condensation can strongly reduce the
torque, or the friction surfaces can freeze up.
The user is responsible for taking appropriate
counter measures.
Appointed Use
ROBATIC®-clutches have been developed, manufactured and
tested as electromagnetic components in compliance with the
DIN VDE 0580 standard and in accordance with the EU Low
Voltage Directive. During installation, operation and maintenance
of the product, the requirements for the standard must be
observed.
ROBATIC®-clutches are for use in machines and systems and
must only be used in the situations for which they are ordered
and confirmed. Using them for any other purpose is not allowed!
Earthing Connection
The clutch is designed for Protection Class I. This protection
covers not only the basic insulation, but also the connection of all
conductive parts to the PE conductor on the fixed installation. If
the basic insulation fails, no contact voltage will remain. Please
carry out a standardized inspection of the PE conductor
connections to all contactable metal parts!
Insulation Material Class F (+155 °C)
The insulation components on the magnetic coils are
manufactured at least to insulation material class F (+155 °C).
Protection
(electrical) IP54: Dust-proof and protected against contact as
well as against water spray coming from any direction.
This protection is valid for the coil, the casting compound and the
connection strands.
On designs with a connection terminal, the connection
terminal itself corresponds to Protection IP00.
Storage of ROBATIC®-clutch Devices
 Store the clutches in a horizontal position, in dry rooms and
dust and vibration-free.
 Relative air humidity < 50 %.
 Temperature without major fluctuations within a range
from – 20 °up to +60°C.
 Do not store in direct sunlight or UV light.
 Do not store aggressive, corrosive substances (solvents /
acids / lyes / salts etc.) near to the clutches.
For longer storage of more than 2 years, special measures are
required (please contact the manufacturer).
Handling
Before installation, the clutch must be inspected and found to
be in proper condition.
The clutch function must be inspected both once installation
has taken place as well as after longer system downtimes, in
order to prevent the drive starting up against possibly seized
friction surfaces.
User-implemented Protective Measures:
 Please cover moving parts to protect against injury
through seizure.
 Place a cover on the magnetic part to protect against
injury through high temperatures.
 Protective circuit: When using DC-side switching, the coil
must be protected by a suitable protective circuit according
to VDE 0580, which is integrated in mayr ®-rectifiers. To
protect the switching contact from consumption when using
DC-side switching, additional protective measures are
necessary (e.g. series connection of switching contacts).
The switching contacts used should have a minimum
contact opening of 3 mm and should be suitable for
inductive load switching. Please make sure on selection
that the rated voltage and the rated operation current are
sufficient. Depending on the application, the switching
contact can also be protected by other protective circuits
(e.g. mayr ®-spark quenching unit, half-wave and bridge
rectifiers), although this may of course then alter the
switching times.
 Install additional protective measures against corrosion if
the clutch is subject to extreme ambient conditions or is
installed in open air conditions, unprotected from the
weather.
 Take precautions against freeze-up of the friction
surfaces in high humidity and at low temperatures.

State of Delivery
Please check the state of delivery immediately according to the
Parts List!
mayr® will take no responsibility for belated complaints.
Please report transport damage immediately to the deliverer.
Please report incomplete delivery and obvious defects to the
manufacturer.
Function
ROBATIC®-clutches are energised to engage, electromagnetic
pole face clutches.
By applying DC voltage to the magnetic coil in the coil carrier (3),
a magnetic field is built up. This attracts the armature disk (9)
against the rotor (1 or 2).
The torque is transmitted via frictional locking.
In new condition, torque transmission first takes
place via the metal external pole on the rotor
(1 or 2) and, after a short operation period, then
additionally via the internal pole. After the entire
run-in procedure, an even frictional combination
occurs on the metal poles and on the friction
lining lying between them.
Design
ROBATIC®-clutches feature electrical Protection IP 54 and
Insulation Material Class F (up to 155 °C) for the coil, the casting
compound and the connection strands.
On designs with a connection terminal, the connection terminal
itself corresponds to Protection IP00.
At a duty cycle of 100%, the coil carrier temperature is approx.
65 °C.
The surfaces of the coil carrier (3), the rotor (1 and 2) and the
driver flange (10) are phosphated, the armature disk (9) is gas
nitro carburated (ground friction surfaces), and the transmission
spring is made of stainless steel.
The clutch rotor (1 or 2) is delivered pilot bored or finish bored
with a keyway acc. DIN 6885. If the rotor bore and keyway are
produced customer-side, the Guidelines on page 6 of the
Installation and Operational Instructions on "Boring the Rotor
Hub" must be observed!
Explanation of Terms
The nominal torque M2is the largest transmittable torque (after
run-in has been completed), with which the closed clutch can be
loaded without slipping occurring.
The friction work Qais the friction work per acceleration.
The relative duty cycle is the ratio of duty cycle to backlash
duration in percent (% duty cycle).
Torque Characteristics
In new condition, c. 50 % of the catalogue nominal torque
(M2) is transmitted.
The components reach the catalogue nominal torque when the
friction surfaces are run in. Please take c. 100 – 200 switching
actions in dynamic operation, a typical speed of c. 500 to 1000
rpm and a medium friction work (see Table 2) as rough reference
values.
Longer slipping on the clutch, especially at low speeds, is to be
avoided, as this can lead to scoring and therefore to damage to
the friction surfaces.
Clutches used in static or virtually static operation do not reach
the nominal torque (M2) stated in the Technical Data (Table 1).
On request, the clutches can be run in manufacturer-side. In this
case, please ensure that the customer-side installation is carried
out exactly according to the specifications, in order to re-create
the best possible friction conditions. Also, the "friction carbon"
must not be wiped away.
If the clutches are run in manufacturer-side to the nominal torque
and then used in static or virtually static operation, please expect
a reduction in nominal torque of c. 60 to 70 %.
This is the case if the clutch under-runs the speed nmin or friction
work Qastated in Table 2.

Run-in Conditions
Please carry out an "artificial" run-in, if a run-in procedure on the
machine is not possible for the application (see section "Torque
Characteristics"). This is the case e.g. when the friction work, the
speed or the switching frequencies are too low.
Run-in Possibility 1
 Apply a voltage of c. 1/3 of Unom
(Do not apply nominal voltage!)
 Speed On Sizes 3 - 6: c. 50 rpm,
On Sizes 7 - 9: c. 30 rpm
 Approx. 2 – 3 minutes slipping against blocked output
Run-in Possibility 2
 Synchronize against unblocked output by producing a larger
rotating mass, and / or synchronize at higher speed (values
should lie above the minimum values stated in Table 2).
 Allow to synchronize c. 2 - 3 minutes
General Installation Guidelines
 Mount or push on the clutch using a suitable mounting
device.
Do not mount onto the shaft by hitting with a hammer.
 Support the coil carrier (3) against twisting (Fig. 3).
 The friction surfaces of the rotor (1 or 2) and the armature
disk (9) must be kept free of oil and grease.
 Remove the clutch from the shaft over the snap ring groove
on the coil carrier (3) using a locking ring (Fig. 4), or over the
tapped holes on the rotor facing side (only on rotor Type
540. 100 / Fig. 5).
The locking ring (Fig. 4) is not included in delivery.
Fig. 3
Fig. 4
Boring the Rotor Hub (Fig. 5)
The rotor (1 or 2) must not be bent during boring. Do not put
pressure on the outer, thin-walled area of the rotor (1 or 2), see
Fig. 5.
In order to bore, clamp the rotor (1 or 2) onto the hub, as
depicted in Fig. 5.
The maximum permitted bore diameter dmax, acc. Table 1, must
not be exceeded.
We recommend H7/k6 as a suitable hub-shaft tolerance.
