BM-E Series


The BM-E series is designed and manufactured to be used in environments with a potentially explosive atmosphere due to the presence of explosive gas and flammable powders.

BM-E series vibrating motors are realised in conformity to the Atex Directive 2014/34/UE and Scheme IECEx, to be used in Zone 1 (Gas) and Zone 21 (Powder).

Types of protection:
Increased Safety and by Enclosures.

S1 Continuous duty at the maximum centrifugal force, with the possibility to adjust the force from 0 to 100% following the specific graded plate on the eccentric weights.

Mechanical Protection
IP 66 according to EN 60529, EN 60529/A1

Impacts Protection

Electric Motor
Electric motor realized with low loss silicium magnetic lamination core, allowing to increase the efficiency while reducing heating up.

Insulation Class

Windings impregnation realized with ASTM system, with polyester resin class H.

Ambient Temperature
From -20°C to +40°C (-4°F/104°F).

PTC Thermistor
Electric motor protected by thermistor (PTC set at 130°C) as standard from size 50 (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).

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, with special “Long-Life” grease lubrication. Labyrinth type bearing seal for grease, with wide restraining chamber.

Available on request
Special fixing holes configurations.
