Western Electric Ex Electric Motors
Western Electric explosion proof motors are distinguished by high material quality, robust design, high index of IP protection, bearings greased for life, weather and corrosion resistant final overcoat and high dielectric strength insulation system intended to be feed by static frequency converter.
Local conditions must be divided in danger zones, defined by end user together with appropriate establishment, according to frequency and duration of appearance of an explosive gas atmosphere.
Three-phase induction TEFC motors, and designed in protection enclosure „d“ may be used in zones 1 and 2 endangered by explosive atmosphere, area of use II (all industry except mining). In these zones such an atmosphere can occur during normal operation (zone 1), or its appearing is not expected and if it does occur, it lasts for short time period (zone 2).
Explosive atmosphere is a mixture of some flammable substances and air in the form of gas, vapour, mist or dust. Named dangerous zones exists in gas plants, paint shops, chemical and pharmaceutical industry, refineries, tankers etc.
Designed according to IEC 60079-0, IEC 60079-1, IEC 60079-70 and IEC 60079-31. Motors of series 1D2 are certified in conformity with last edition of IEC, Australian Standards.
All our flameproof motors series 1D2 have the highest explosion group IIB, temperature classes T1 to T5 at ambient temperatures from -20 to +60 °C. Declaration of conformity for the motors and Operating Instructions are supplied as standard with explosion-proof motors in English.
Western Electric Ex Electric Motors are used within a wide variety of applications in hazardous areas. Some of the typical applications are listed below:
