Motors, flame proof

SPM Engg Industries manufactures flameproof motors that find application in coalmines, refineries, petrochemical industries and others where flammable gases, vapours, fumes and coal dust are natural atmospheric hazards. These motors can be used in all divisions, certain division II areas and I as laid down in guide for selection of electrical equipments in hazardous areas as per IS: 5571:1979. The flameproof enclosure consists of sturdy cast iron parts, which are mechanically robust and very liberally designed. The cast iron enclosure is built to withstand any internal explosion. The gaps of joints and where the shaft passes through the frame are so dimensioned as to prevent transmission of igniting flame to the surrounding atmosphere. The motors are so designed that the frame temperature will remain below the ignition temperature of the gas-air mixture involved.
