Flame Proof Motor EXD I, IIA & IIB
An explosive atmosphere is one where a mixture with air under atmospheric conditions of flammable substances in the form of gas, vapour or mist, exists in such proportion that it may explode due to excessive temperature, arcs or sparks. Flameproof motors were once manufactured with an enclosure constructed in such a manner that any explosion inside is not capable of igniting an explosive atmosphere outside the enclosure, and the surface temperature is safe enough not to ignite the outside explosive atmosphere.
Features
The winding insulation system is class F in accordance with IEC 85.
All rotors are dynamically balanced with half key to ensure normal class of vibration level as per IEC®* 60034-14.
Motors can be wound for any voltage from up to 6.6KV and for 50 Hz frequency with preferred voltage of 415V, 690V, 3300V, 6600V.
Motors are suitable for operation ±10% voltage variation and ±5% frequency variation with permissible combined variation of 10%.
Noise level for flameproof motors conforms to the requirement of IEC 60034-9.
All standard motors are suitable for withstanding mechanical over the speed of 120 % for 2 Minutes.
