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 “drop by
drop” trickle system.
Ambient temperature
From -20°C to +40°C. Versions for higher
or lower temperatures are available on
request.
Vibrator thermal protection
Standard PTC rated thermistor heat detec-
tors 130°C (DIN 44081-44082) from size 70,
on request for smaller sizes. On request,
thermistors with different temperatures
and anti-condensation heaters.
Fixing of the vibrator
In all positions and therefore without
restriction.
Lubrication
All vibrators are correctly lubricated in
the factory and do not require further
lubrication if used in normal operating
conditions (”FOR LIFE” lubrication).
In heavy duty operating conditions perio-
dical re-lubrication may be applied.
Terminal box
Large fixed electrical connections. 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 vibrating machi-
nes. Insulated windings using the “drop by
drop” trickle system with class H resin.
The rotor is die cast aluminium.
Casing
In spheroidal cast iron to have high
strength and optimal elasticity. Patented
shape that improves heat dispersion and
lowers normal working temperature at
full load.
Bearing flange
Constructed in cast iron (spheroidal
or grey). The geometry of the flange
transmits the load to the casing uni-
formly.
Bearings
Custom made with particular geometry,
especially designed for Italvibras, suitable
to support both high radial and axial
loads.
Split covers
The MVSI-TS series, obtained directly from the MVSI series,
is characterized by the split weight covers. The weight
cover is divided into two halves that can be removed in a
radial direction. According to requirements it is possible to
mount one or two split weight covers.
The MVSI-TS series is indispensable in those applications
where the position of the vibrator in the vibrating machine
makes it difficult to axially remove the weight cover, while
it has space to carry this out in a radial direction.
The
MVSI-TS series complies with the most recent IEC and
EN international standards for use in atmospheres with
potentially explosive powders.
In particular, the MVSI-TS series can be used in areas 21 and 22.
Technical features
Power supply
Three-phase voltage from 48V to 690V,
50Hz or 60Hz; suitable for use with an
inverter from 20Hz to the base frequency,
with constant torque load profile.
Polarity
4, 6 and 8 poles.
Conformity with European Directives
Low Voltage 2006/95/EC, ATEX 94/9/EC.

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 infor-
mation contact our technical assistance
office.

Range extended up to 25000 Kgf. (245 KN),
with centrifugal force adjustable from 0
to 100%.
Mechanical protection
IP 66 according to IEC 529, EN 60529.
