Vertical electric vibrator VB


Specifications of Vibrating motors VB



Description


The VB series is made up of vertical vibrators with double conical flange. These vibrators are typically used in circular screens and in medium-size and large sieves. They are supplied without eccentric weights, which must be realised and mounted by the manufacturer of the vibrating machine. The VB series complies with the most recent IEC and EN international standards for use in atmospheres with potentially explosive powders. In particular, the VB series can be used in areas 21 and 22.


Power supply


Three-phase voltage from 220V to 690V, 50Hz or 60Hz; suitable for use with an inverter from 20Hz to the base frequency with constant torque load profile


Polarity


4 and 6 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 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


Proportioned for a centrifugal force equal to 5000 Kgf. (49 KN), with eccentric weights not included, to be made by the user.


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), class H (180°C) on request.


Tropicalization


StaStandard 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


On PTC rated request with thermistor heat detectors 130°C (DIN 44081-44082). 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 if used in normal operating conditions (“FOR LIFE” lubricatIon). In heavy duty operating conditions periodical re-lubrication may be applied.


Terminal box


The 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 using “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.


Bearing flange


Constructed in spheroidal cast iron. The geometry of the flange transmits the load to the casing uniformly.


Bearings


Custom made with particular geometry, especially designed for this vibrator, suitable to support both high radial and axial loads.


Motor shaft


In treated steel alloy (Isothermic hardening) resistant to stress.


Eccentric weights


Not envisioned, to be made and mounted by the user.


Weight covers


Not envisioned.


Painting


Electrostatic surface treatment based on polymerised epoxy polyester powder in oven at 200°C. Tested in salt spray for 500 hours.


Stainless steel protection


On request, corrosion high grade protection (stainless steel micro suspensions in a polyurethanic paint) is available.
