BRUSHLESS SERVOMOTORS - ATEX - OPERATING INSTRUCTIONS – 3010/21
1
Read these Operating Instructions before performing any
transportation, installation, commissioning, maintenance or repair
activities on the industrial motors and generators.
The instructions contained in this manual cannot provide all the
detailed information on the possible construction variations, nor every
possible case regarding assembly, operation and maintenance.
The symbols provided below will draw attention to the safety
measures and supplementary instructions contained in these
Operating Instructions.
SPECIAL SAFETY AND WARRANTY
INSTRUCTIONS:
DANGER:
NOTE ON EXPLOSION PROTECTION
Strictly observe the safety measures and supplementary instructions
contained in these Operating Instructions, for the protection of
property and people.
Low-voltage electric machines contain dangerous rotating
and conductive parts. They may have very hot surfaces.
All the transportation, installation, commissioning,
maintenance and repair activities must be carried out by
qualified personnel and under the supervision of experts
in charge (in conformity with directives VDE 0105; IEC
364). Improper use of the mentioned machines can
cause serious damage to property and people
.
To receive further information, contact the manufacturer or an
authorised workshop immediately.
All motors and generators must be installed and used
exclusively by qualified personnel.
GENERAL INFORMATION
SCOPE
These instructions refer to three-phase servomotors powered by drives
generating alternate current, at low voltage and with external
ventilation, with protection degree up to IP65, in accordance with
standards EN 60034.
The motors comply with the requirement of industrial installations, in
accordance of DIN harmonising standards VDE0530/EN60034. It is
compulsory to follow any special instructions regarding their use.
Brushless servo motors, with external ventilation, are designed to
operate at a maximum altitude of ≤ 1000 m above sea level and at
ambient temperature between – 20°C and + 40°C. The motor shall
not be exposed to direct sun light.
Observe the information provided on the rating plate. The
operating conditions must line up with the data reported
on the rating plate.
Brushless servo motors are part of a machine, according to Directive
Machines 2006/42/EC. It is forbidden to commission the machine if
the final product does not fulfil this standard (EN 60204-1).
TRANSPORT
Any damage discovered on delivery must be immediately reported to
the delivery company. Do not commission the machine.
LIFTING EYEBOLTS
Lift the motors exclusively by the relative lifting eyebolts
provided for this purpose. Do not add loads to the motor.
The lifting eyebolts are designed to support only the
weight of the motor. Should it be necessary, use
appropriate jacks, slings and lifting beams?
INSTALLATION AND COMMISSIONING
NOTE ON EXPLOSION PROTECTION
The installation shall comply with standard 60079-14
for setting electrical machinery
MECHANICAL PARTS
TRANSMISSION ELEMENTS
Use elastic couplings only. Rigid couplings require a
special bearing design.
The use of transmission elements that cause radial or axial shaft loads
during operation (pulleys, gearwheels, etc.), requires checking
compatibility with admissible motor loads. Relevant data is contained
in the respective technical catalogue.
Rotors are dynamically balanced with half key, in conformity with
standard DIN ISO 8821.
When the motor is balanced with a half key (H), the coupling has also
to be balanced in the same way. Remove the overhanging visible part
of the key.
Remove anti-corrosion paint using specific solvent and grease the
shaft extension. Only use suitable tools to mount or pull off pulleys or
couplings, as illustrated in figure 1 (warm up if necessary) and use a
protective cover against any accidental contact. Avoid inadmissible
tension of the belts (technical catalogue). It is necessary to use the
intermediate disc to protect centring on the shaft end.
If necessary, completely balance the motor with the pinion according
to standard ISO1940.

The bearings must strictly not be subject to pressure or impact.
COUPLINGS
Transmission of the machine's rotating motion can be carried out
through direct coupling or through belts and gears.
Make sure the selected transmission gears can transmit
the maximum torque delivered by the motor and support
the pre-selected maximum operating speed. Sizing the
pinion must be done with an ample safety margin in mind.
