Power supply Three-phase voltage from 24V to 690V, 50Hz or 60Hz or single-phase 100-130V, 60Hz and 200-240V, 50Hz (single-phase types are supplied without capacitor); suitable for use with an inverter from 20Hz to the base frequency with constant torque load profile. Polarity 2, 4, 6 and 8 standard poles, 10 and 12 poles on request. Conformity with Standards and Regulations Low Voltage Directive 2006/95/EC; ATEX Directive 2014/34/UE; EN/IEC 60034-1, EN/IEC 60079-0, EN/IEC 60079-31, UL 1004-1, CSA C22.2 No.100, NEMA MG-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 Range extended up to 30500 kgf. (300 kN), with centrifugal force adjustable by varying eccentric weights position. Mechanical protection IP 66 according to IEC/EN 60529.Protection against mechanical impacts IK 08 according to IEC/EN 62262. Insulation class Class F (155°C), class H (180°C) on request. Tropicalization Standard on all vibrators, with vacuum encapsulation up to gr. AF 33 and 35, with “drop by drop” trickle system for larger sizes. Ambient temperature From -20°C to +40°C. Versions for higher or lower temperatures are available on request. Vibrator thermal protection Standard PTC rated thermistor heat detectors 130°C 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 at start-up. Terminal box Large terminal box to facilitate electrical connection. Special shaped terminals allow for the power supply cable to be secured, whilst protecting it from loosening. Electric motor Three-phase asynchronous type. Designed for maximum starting torques and torque curves specific to requirements of vibrating machines.
