ISIL is now being used by the U.S State Department as well as the United Nations, since the group wants to extend that influence even further. That reach is called (in Arabic), al-Dawla al-Islamiya fi Iraq wa al-Sham, the English equivalent of which is the Levant. Therefore they are the Islamic State of Iraq and the Levant, or ISIL.
(4) Rotor / Armature: Conversion of DC Current to AC Voltage â The rotor / armature now induces a larger AC voltage across the windings of the stator, which the generator now produces as a larger output AC voltage. This cycle continues till the generator begins to produce output voltage equivalent to its full operating capacity.
There are some common properties of armature winding. 1  First and most important property of an armature winding is, two sides of any coil should be under two adjacent poles. 2  The winding can either be single layer or double layer. 3  Winding is so arranged in different armature slots, that it must produce sinusoidal emf.
