WebAug 23, 2016 · A short pitched coil is also known as Chorded Coil. Chording Angle ξ is defined as the angle by which the coil span departs from a pole pitch i.e. 180 degree. …
[Solved] Short pitched coils are deliberately used in an alternator,
WebThe advantage of using short pitched windings in an alternator is that it (A) suppresses the harmonics in generated emf (B) reduces the total voltage around the armature coils (C) saves copper used in windings (D) improves cooling by better circulation of air. 113. WebIn an alternator, the pitch factor is the ratio of the e.m.fs. of 44. The power factor of an alternator is determined by its 45. If the input to the prime mover of an alternator is kept constant but the excitation is increased, then 46. In an alternator zero power factor method is used to find the 47. destination meaning in gujarati
