Explosion proof induction three phase squirrel cage rotor motors series VA are designed for applicable for equipments with explosive gas environment except coal mine,with high protection level,it is not a source of ignition during normal running or under expected fault conditions, Motors are designed for operation at
voltage of 220,380,660,1140V from the 50 Hz AC mains.
cast iron body.
Climatic versions of motors -U1.
The rated duty -continuous S1.
Type of construction -IM1001,IM2001,3001.
Cooling method-IC411.
Degree of motor protection: IP55,IP56,IP66.
Motors are designed for direct-on-line starting. Motors allow two successive startings when cold or one starting when heated. Subsequent startings should be made with at least three hours intervals, number of startings not less than 2000 for service life, but not more than 250 startings during a year.
Motors are equipped with grease lubricated rolling contact bearings.
Motors are coupled with the driven mechanism with a help of flexible coupling. The stator winding insulation is F. Type of heat resistance is not lower than "B". Stator winding has six leads brought out to four insulators in the terminal box. Stator windings are delta/star connected.
Motors allow both clockwise and counterclockwise rotation.
