M3
Designed for industrial continuous duty, the M3 series
features a compact shape, reduced overall dimensions, ter-
minal box underneath which means also a high electric pro-
tection in dusty environments. Multi-holes mounting feet
enable M3 series to match several existing mounting plates.
M3 series motors comply with the most recent international
standards for use in explosive dust atmospheres. Particular-
ly M3 series can be used in zones 21 and 22.
Technical features
Power supply
Three-phase voltage from 24V to 690V,
50Hz o 60Hz or single-phase 100-130V,
60Hz and 200-240V, 50Hz; suitable for use
with an inverter from 20Hz to the base
frequency with constant torque load
profile.
Polarity
2 and 4 poles.
Conformity with European Directives
ATEX 94/9/EC.
Low Voltage 2006/95/EC.
Reference Regulations
IEC/EN 61241-0, IEC/EN 61241-1,
EN 60034-1.
Functioning
Continual service (S1) at maximum decla-
red centrifugal force and electric power.
Intermittent services are also possible
depending on the type of vibrator and
the operating conditions. For detailed
information contact our technical assi-
stance office.
Centrifugal force
Range up to 311 kgf (3.05 kN). Centrifugal
force can be changed by adjusting the
eccenctric weights
Mechanical protection
IP 66 according to IEC 529, EN 60529.
Protection against mechanical impacts
IK 08 according to IEC 68, EN 50102.
Insulation class
Class F (155°C).
Tropicalization
Standard with vacuum encapsulation.
Ambient temperature
From -20°C to +40°C. Versions for higher
or lower temperatures are available on
request.
Vibrator thermal protection
On request with PTC thermistor rated
heat detectors 130°C (DIN 44081-44082).
Fixing of the vibrator
In all positions and therefore without re-
striction. The terminal box is positioned
underneath the vibrator, on the same
side as the fixing base.
Lubrication
Sealed ball bearings, lubricated “for life”.
Terminal box
The terminal box is positioned under-
neath the vibrator, on the same side as
the fixing base. Special shaped terminals
allow to fix the power supply cable, pro-
tecting it from loosening.
Electric motor
Three-phase or single-phase asynchro-
nous type. Insulated windings using
vacuum encapsulating.
The rotor is die cast aluminium.
