Introduction
The BMF vibrators of the sizes 00 to 04 are provided with eccentric masses on both sides of the shaft and a single side cover on the side opposite to that of the connection flange.
The BMF vibrators of sizes 15 to 70 are NOT provided with eccentric masses, nor with side protection covers. On request we can supply adjustment bushes with graduated plates, eccentric masses and weight protection covers.
Characteristics
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 power supply
Standard executions 50Hz 220-230 / 380-400V; 60Hz 220-240 / 440-480V (for EVR-EVS series 50Hz 380-400V; 60Hz 440-480V). Special voltages available on request.
Speed (vibrations per minute)
Standard: | 2 poles: 3000 rpm – 50Hz | 3600 rpm – 60Hz | (BMF sizes from 00 to 04; BMF-ST) |
4 poles: 1500 rpm – 50Hz | 1800 rpm – 60Hz | (BMF; BMF-C; BMF-ST; EVR; EVS) | |
6 poles: 1000 rpm – 50Hz | 1200 rpm – 60Hz | (BMF sizes from 15 to 70; EVR; EVS) |
On request
Speed not foreseen by the standard. Double speeds 3000 / 1500rpm or 1500 / 1000rpm
Operation
Continuous service at maximum centrifugal force (S1), with the possibility of adjusting the force from 0 to 100% by following the appropriate reference plate on the eccentric masses (for the series / models supplied by DPH Engineering complete with masses).
Electric Motor Electric
motor made with low-loss silicon magnetic steel laminations, which make it possible to increase its efficiency by containing heating. Starting torques and high powers.
Insulation class
F standard, H on request.
Tropicalisation
Impregnation of the winding made with the ASTM method, with class H polyester resin.
Ambient Temperature
From -20 ° C to + 40 ° C (-4 ° F / 104 ° F).
Overheating Protection
Electric motor protected by thermistor (PTC set at 130°C) as standard for sizes 50 and 70 (available on request on smaller sizes).
Motor Shaft
Shafts in NiCrMo steel, heat treated.
Main Body
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).
Painting
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.
