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.

Objective Questions on Alternators Part 4

WebAn alternator or a synchronous generator is a device used to convert mechanical energy to Alternating current electric current. The EMF equation of an alternator is a mathematical … WebAnswer: Probably to minimize the number of turns used per coil, which may be reflected as a bit lower output, while maximizing its exposure to an almost overlapping of magnetic fields…. Since using less copper will also lower any associated copper losses, thus reducing harmonics which in turn wil... daniel tiger\u0027s neighborhood songs archive

Armature Winding of Alternator Electrical4U

WebJul 27, 2024 · In unbalanced winding, the each pole contains unequal number of coils in different phases. But there should be equal number of coils in each phase. Full pitch and short pitch winding. When the two coil sides forming a complete coil of a winding are 180 electrical degrees apart, the winding is called as full pitch winding. WebAug 22, 2024 · Short pitched coils are deliberately used in an alternator, because: they improve the waveform of the generated EMF they save copper of end connections eddy … WebIn an alternator short pitch coils are used A. to reduce the stray losses B. to reduce the size of the machine C. to provide accurate phase difference of 1200 between each phase D. to … daniel tiger\\u0027s neighborhood tea party game
