The double-conical flange Italvibras VB-E electric vibrators have been designed for use in industrial processes in environments with a potentially explosive atmosphere, caused by gas and dusts, in compliance with ATEX Directive (94/9/EC). They are supplied without eccentric weights, which must be realised and mounted by the Manufacturer of the vibrating machine. In particular, these vibrators can be used in areas 1 and 2 (gas) and in areas 21 and 22 (dusts).

Power supply
Three-phase voltage from 220V to 690V, 50Hz or 60Hz; suitable for use with a PWM frequency drive from 20Hz to the base frequency with constant torque load profile

Polarity
4 poles.

Functionality
Continual service (S1) at maximum declared centrifugal force and electric power.

Centrifugal force
Proportioned for a centrifugal force equal to 2500 Kgf. (24.5 KN)

Classe d’isolamento
Classe F (155°C).

Electric motor
Three-phase asynchronous type. Insulated windings using “drop by drop” trickle system with class H resin.
