MVCC Direct Current Electric Vibrators

by Italvibras

The MVCC series of vibrators in direct current has been designed for use in those situations where network electricity is not present.  In particular for hoppers, silos and gate-controls and roll-on-roll-off vehicles (concrete mixers, pumps for concrete, plasterers, salt distributors, gravel spreader, fertilizer spreader, hauled silos, industrial sweeper filters).  The newly-conceived electric motor, with permanent magnet poles, and the increase in size of the electrical parts, allow constant, high yielding performance.  

The MF models have a multi-hole fixing base to adapt to different centre distances of drilling.

Technical features

Power supply

In direct current at 12 or 24V

Conformity with European Directives

Electromagnetic compatibility 2004/108/EC.

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, please contact our office.

Centrifugal force

Range extended up to 1520 Kgf. (14,9 KN), with centrifugal force adjustable from 0 to 100%.

Mechanical protection

IP66 according to IEC 529, EN 60529.

Protection against mechanical impacts

IK08 according to IEC 68, EN 50102.

Ambient temperature

From -20°C to +40°C.

Fixing of the vibrator

In all positions and therefore without restrictions.

Lubrication

Sealed ball bearings, lubricated "for life".

Terminal box

On MF models, it's positioned underneath the vibrator, on the same side as the fixing base.

Electric motor

Direct current with permanent magnet poles.  The rotor is a wound brush-type with collector.

Casing

In high-tensile aluminium alloy.

Bearing flange

Constructed in aluminium with steel bearing seat.  The geometry of the flange transmits the load to the casing uniformly.

Motor shaft

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

Eccentric weights

Enable continuous adjustment of the centrifugal force.  The adjustment is facilitated by a graduated scale that expresses the maximum centrifugal force.  A patented system (patent N°MO98A000194) called ARS prevents adjustment errors.

Weight covers

In alluminium alloy.

Painting

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

Other features

All MVCC electric vibrators have been tested in semi-anechoic chamber to verify conformity with the standards and directives on electromagnetic compatibility. The MVCC series is supplied with a special high-resistance synthetic rubber power supply cable measuring 2.5 mtr.
