Power supply Three-phase voltage from 220V to 690V, 50Hz or
60Hz; variable frequency (in presence of PTC thermistor) from 20Hz to the base
frequency with constant torque load profile tipo PWM. Polarity 2, 4, 6 and 8
poles. Conformity with Standards and Regulations ATEX Directive 2014/34/UE;
EN/IEC 60079-0, EN/IEC 60079-7, EN/IEC 60079-31, EN/IEC 60034-1. Controls The
components that affect protection are 100% accurately controlled and recorded.
Functioning Continual service (S1) at maximum declared centrifugal force and
electric power. Centrifugal force Range extended up to 11160 kgf. (109 kN),
adjustable in a continuous linear mode with variation of the position of the
eccentric weights. Mechanical protection IP 66 according to IEC/EN 60529.

Protection against mechanical impacts IK 08 according to
IEC/EN 62262. Insulation class Class F (155°C). Tropicalization Standard on all
vibrators, with vacuum encapsulation up to size AF 33 and 35, with “drop by
drop” trickle system for larger sizes. Ambient temperature From -20°C to +40°C,
on request it is possible to have vibrators for max. ambient temperatures of
+55°C. Vibrator thermal protection Standard PTC rated thermistor heat detectors
130°C 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 lubricated
in the factory and do not require further lubrication at start-up.

Terminal box Large terminal box to facilitate
electrical connection. Special shaped terminals allow for the power supply
cable to be secured, whilst protecting it from loosening. Electric motor
Three-phase asynchronous type. Designed for maximum starting torques and torque
curves specific to requirements of vibrating machines.
