What is a armature |
| Answer» The\xa0field\xa0of a synchronous generator is the winding to which the DC excitation current is applied. The\xa0armature\xa0is the winding to which the load is connected. In small generators, the\xa0field\xa0windings are often on the stator, and the\xa0armature\xa0windings are on the rotor.\xa0The core of an\xa0armature\xa0is\xa0made up\xa0of lots of thin metal plates called laminations, which are usually about 0.5mm thick. The thickness of laminations depend upon the frequency at which the\xa0armature\xa0is designed to work. Laminations are stamped\xa0out\xa0on a press. | |
