BMF vibrators of sizes from 00 to 04 are provided as standard with excentric weights on both sides of the shaft and with one only weight cover on the opposite side of the fixing flange.
BMF vibrators of sizes from 15 to 70 are NOT provided with eccentric weights, NOR weight protection covers. On request they can be supplied with regulation bushes with graded disc, eccentric weights and weights protection covers.
OMB manufactures a wide range of vibrating motors with flange fixation, covering all the applications needs on vibrating equipments for screening, finishing, drying and other processes that use vibrating motors with this fixing system.
Three-phase Input Voltage:
Standard executions 50Hz 220-230/380-400V; 60Hz 220-240/440-480V (for series EVR-EVS 50Hz 380-400V; 60Hz 440-480V). Special input voltages available on request.

Speeds not listed as standard Two speeds motors 3000/1500rpm or 1500/1000rpm
Continuous duty at the maximum centrifugal force (S1), with the possibility to adjust the force from 0 to 100% following the specific graded plate on the eccentric weights (for those series/models supplied by OMB complete with weights).
Electric motor realized with low loss silicium magnetic lamination core allowing to increase the efficiency while reducing heating up.
F standard, H on request.
Windings impregnation realized with ASTM system, with polyester resin class H.
From -20°C a +40°C (-4°F/104°F).
Electric motor protected by thermistor (PTC set at 130°C) as standard for sizes 50 and 70 (available on request on smaller sizes).
Shafts in NiCrMo steel, heat treated.
Mechanical structure designed to withstand the high stresses, realized in cast iron (starting from size 03) or in high resistance aluminum (up to size 02).
Electrostatic powder painting, epoxy-polyester, polymerized in oven. Color: Blue RAL 5010.
Bearings and Lubrication
High load capacity bearings, in special executions to withstand the stresses of high centrifugal forces and vibrations, over-dimensioned to grant maximum reliability in vertical use. Special “Long Life” grease lubrication. Mechanical seals with low friction to grant excellent protection, without over-heating and without extra power absorption, keeping their efficiency for long time. Some models as a standard, others on request, are provided with bearing housing with double lubrication entry, to grant that lubrication grease inlet is always from upper side of the bearing.
