1.2 Main characteristics
• Explosion-proof motors according to
European standard CENELEC EN 50 014,
EN 50 018 and EN 50 019 (for terminal
box EEx-e).
• The European Standards are known and
accepted by most Countries world-wide
besides CENELEC (European Committee
for Electrotechnical Standardization)
member countries.
• Three phase and single phase Squirrel
Cage Asynchronous Induction motors.
• Totally enclosed, fan cooled, frame IP55
with Terminal box IP65.
• The motors dimensions comply with
IEC 60072 standard.
• Power Supply 400V / 50Hz.
Three-phase, 1-speed motors, 2-4-6-8
poles, T4, for sizes between 56 and 80,
multi-voltage power supply
380-400-420V/ 50 Hz.
• Class F insulation.
1.3 Main options
• Non-standard voltages and frequencies
(maximum voltage 690V).
• Motors with special electrical design.
• Motors suitable for frequency inverter
drive.
• Special flanges and shafts.
• Double ended shafts.
• Grade R and S balancing.
• Large motors with special bearings
(unidirectional).
• Noise level (dBA)
Noise values measured both loadless and
at the rated power supply condition are
lower than those set forth by the
NF 51-119 Standard (IEC 34-9).
We can also provide special applications.
• Terminal Box:
- available both in a flameproof version, or
in an increased safety version
- large size
- normally installed on the side opposite the
feet, can be oriented right- or leftwards
frame separation grid
- rotating by 90° in 4 positions
- frame separation grid.
• Motor frame:
- cooling fins
- removable feet
- pad for direct frame connection
- removable through hole flange
- front and back lip seal (IP55)
- earthing screw.
• Rotor:
- in pressure cast aluminium alloy
- shaft mounting by ring nut
- dynamic balanced with feather key fully
seated
- insulating paint.
• Motors protection IP56 - IP65 - IP66.
• Tropicalised motors (relative humidity level
H% including between 90 and 98%).
• Motors with bi-metallic detector
thermistors, PTC thermistors or PT100
resistive sensors (a second cable gland is
supplied).
• Motors with heaters.
• Motors with rain cap.
• Increased safety "e" terminal box, see
chap. 2.5.
• High protection against corrosion:
- stainless steel nameplate
- anticorrosion plated fasteners.
• The following parts are highly resistant to
impact:
- cast aluminium fan cover.
• Low friction dust seals.
• Vibration level:
the dynamic balancing of the rotors (half
spline) allows for a level of residual
vibrations in three-phase motors which
corresponds to the N degree (normal)
according to IEC 34-14.
• The conformity certificates also cover
design characteristics that differ from the
basic version, such as:
- modification of the maximum installation
altitude
- modification of the rated voltage and
rated frequency
- power supply from an inverter
- motor protection through temperature
detectors
- application for operating modes S2 to S9.
• Terminal box with special cable entries.
• Motors without terminal box, with cable
output.
• Motors with tacho-generator or encoder.
• Motors for areas classified as zone 21
and zone 22 (Dust).
• Motors for special applications available
on request.
