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, other polarities on
request. onformity with Standards and Regulations Low Voltage Directive
2006/95/EC; ATEX Directive 2014/34/UE; EN/IEC 60034-1, EN/IEC 60079-0, EN/IEC
60079-31, UL 1004-1, CSA C22.2 No.100, NEMA MG-1. Functioning Continual service
(S1) at maximum declared 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 assistance office.
Centrifugal force Range extended up to 2615 kgf. (25.7 kN), with centrifugal
force adjustable by varying weights position. Mechanical protection IP 66
according to IEC/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/EN 62262. 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. Also 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. Electrical connection box The small size guarantees
passage of tools used for fixing the vibrator to the vibrating machine. The
electrical connection must be carried out using the relative connectors
inserted inside the connection box. Special shaped terminals allow to fix the
power supply cable, protecting it from loosening. Electric motor Three-phase
asynchronous type. Designed 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 larger sizes. 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 bearing seat.
