What does “explosion-proof” actually mean for an electric motor?<\/h3>\n

An explosion-proof motor (flameproof type “d” per IEC 60079-1) does not prevent an internal explosion from occurring. Instead, the motor enclosure is designed to withstand an internal explosion and to cool the escaping gases through precision-machined flamepath gaps so that they cannot ignite the surrounding flammable atmosphere. The enclosure contains the explosion \u2014 it does not prevent it.<\/p>\n<\/div>\n
