BKHH
The MVSS stainless steel series vibrators are characterized by their total pro-
tection from liquids, dusts, aggressive agents and contaminants, thanks to the stainless steel casing and external components.
Insulation class Electric motor
Technical features
Class F (155°C), class H (180°C) on request. Three-phase and single-phase asynchro-nous type. Designed for maximum starting torques and torque curves specic to 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. Tropicalization Power supply Standard on all
vibrators, with vacuum impre-gnation up to size AF 33 and 35, with “drop by drop” trickle system for larger sizes. ted scale, which expresses the centrifugal force as a percentage of the maximum centri-fugal force.A patented system (patent N°MO98A000194), called ARS, prevents adjustment errors. Three-phase voltage from 24V to 690V, 50Hz or 60Hz or single-phase 100-130V 60Hz and 200-240V, 50Hz; suitable for use with an inverter from 20Hz to the base frequency with constant torque load prole.

vibrator The lower and upper bearings have been stu-died to support the relative load and therefore they have a particular geometry, especially designed and made for Italvibras. In stainless steel AISI 304. Functioning In all positions and therefore without restriction. Continual service (S1) at maximum declared centrifugal force and electric power. Intermittent services are also possible depen-ding on the type of
vibrator and the operating conditions. For detailed information, contact our technical assistance oce. Other features Lubrication Motor shaft Identi cation plate in AISI 316L stainless steel. All
vibrators are lubricated in the factory and do not require further lubrication if used in normal operating conditions. In heavy duty operating conditions periodical re-lubrication may be applied to size 35 and larger. In treated steel alloy (Isothermic hardening) resistant to stress. Eccentric weights Allow continual adjustment of the centrifugal force. This adjustment is realized by a gradua- Centrifugal force Range extended up to 4300 Kgf. (42.4 KN), with centrifugal force adjustable from 0 to 100%. Terminal box Mechanical protection Large xed electrical connections, with terminal board cover in stainless steel AISI 316L. Special shaped terminals allow to x the power supply cable, protecting it from loosening. IP 66 according to IEC 529, EN 60529.
