Vibrating motor ATEX EEX-e G/D MVSI-E


Specifications of vibrators MVSI-E



Description


The MVSI-E series has been designed for use in industrial processes in environments with a potentially explosive atmosphere, due to the presence of explosive gas and dust, in compliance with ATEX Directive (94/9/CE). In particular, the MVSI-E series can be used in areas 1 and 2 (gas) and in areas 21 and 22 (dusts) according to the layout and following features:


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 type PWM.


Polarity


2, 4, 6 and 8 poles.


Conformity with European Directives


ATEX 94/9/EC; Low voltage 2006/95/EC.


Reference Regulations


IEC/EN 60079-0, IEC/EN 60079-7, IEC/EN 61241-0, IEC/EN 61241-1, EN 60034-1.


Control


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 529, EN 60529.


Protection against mechanical impacts


IK 08 according to IEC 68, EN 50102.


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 -10°C to +40°C, on request it is possible to have vibrators for max. ambient temperatures of +55°C. On request special greases for temperatures lower than –10°C.


Vibrator thermal protection


Standard PTC rated thermistor heat detectors 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 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 to size 35 and larger.


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. Designed for maximum starting torques and torque curves specific to requirements of vibrating machines. Insulated windings using vacuum encapsulating up to size 35; using the “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 60, in spheroidal cast iron for larger sizes. Patented shape that improves heat dispersion and lowers normal working temperature at full load. An external earthing screw is located on the casing as prescribed by Regulation IEC/EN 60079-0.


Bearing flange


Constructed in cast iron (spheroidal or grey) or in aluminium with steel bearing seat. 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


Allow continual adjustment of the centrifugal force. This adjustment is realized by a graduated scale, which expresses the centrifugal force as a percentage of the maximum centrifugal force. A patented system (patent N°MO98A000194), called ARS, prevents adjustment errors.


Weight covers


In aluminium alloy.


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.
