Power supply
Three-phase voltage from 24V to 690V,
50Hz or 60Hz or single-phase 100-130V,
60Hz and 200-240V, 50Hz (single-phase
types are supplied without capacitor);
suitable for use with an inverter from
20Hz to the base frequency with constant
torque load profile.
Polarity
2 or 4 poles.
Conformity with European Directives
Low Voltage 2006/95/EC,
ATEX 94/9/EC.
Reference Regulations
EN 60034-1,
IEC/EN 61241-0, IEC/EN 61241-1
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 extended up to 2615 Kgf. (25.7 KN),
with centrifugal force adjustable from 0
to 100%.
Mechanical protection
IP 66 according to IEC 529, EN 60529.
Mechanical protection is ensured in the
mounting phase of the vibrator onto the
vibrating machine, by introducing the
special seal into the seat on the coupling
flange.
Protection against mechanical impacts
IK 08 according to IEC 68, EN 50102.
Insulation class
Class F (155°C), class H (180°C) on request.
Tropicalization
Standard on all vibrators, with vacuum
encapsulation up to size 30, with “drop
by drop” trickle system for larger sizes.
Ambient temperature
From -20°C to +40°C. Versions for higher
or lower temperatures are available on
request.
Vibrator thermal protection
On demand with PTC rated thermistor
heat detectors 130°C (DIN 44081-44082).
Also on request thermistors with diffe-
rent temperatures and anti-condensation
heaters.
Fixing of the vibrator
In all positions and therefore without
restriction.
Lubrication
All vibrators are lubricated in the factory
and do not require further lubrication
if used in normal operating conditions
(“FOR LIFE” lubrication).
In heavy duty operating conditions pe-
riodical re-lubrication may be applied to
frame sizes 40-50-70.
Electrical connection box
The size guarantees passage of tools
used for fixing the vibrator to the vibra-
ting machine. The electrical connection
must be carried out using the relative
connectors inserted inside the connec-
tion box. Special shaped terminals allow
to fix the power supply cable, protecting
it from loosening.
Electric motor
Three-phase asynchronous type. Desig-
ned for maximum starting torques and
torque curves specific to requirements of
vibrating machines. Insulated windings
through vacuum encapsulating up to size
30; using “drop by drop” trickle system
with class H resin for sizes 40-50-70. The
rotor is die cast aluminium.
Casing
In high-tensile aluminium alloy up to size
50, in spheroidal cast iron for size 70.
Bearing flange
Constructed in cast iron (spheroidal or
grey) or in aluminium with steel bea-
ring seat. The geometry of the flange
transmits the load to the casing uni-
formly.
Technical features
The new MTF (MTF-S02) series, made up of vertical vibrators
with lateral flange and with weight protection covers fixed
to the opposite part to the flange, adopts innovative tech-
nical solutions that increase performance and reliability.
Typically used in circular screens and in small and medium-
size sieves, these vibrators are supplied with lamellar or
clamped eccentric weights, which regulation is particularly
easy.
The MTF series complies with the most recent IEC and EN
international standards for use in atmospheres with poten-
tially explosive powders. In particular, the MTF series can be
used in areas 21 and 22.
