Solved 2. A 25cps single-phase, 8-pole, alternator with 725 - Chegg

WebChording factor =cos (na/2) so to eliminate particular harmonics angle should be 90 °. Where “n” is nth harmonics and “a” is the chording angle. For example, to eliminate 5th harmonics a should be 36°. As windings are chorded so copper savings. Machine cost reduces. As less copper is used so copper losses will be less. Hope this will help.
