Three Phase Motors

The flameproof enclosure consists of sturdy cast iron parts, which are mechanically robust & very liberally designed. The cast iron enclosure of motors is built to withstand any internal explosion. The gaps of joints & 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.
