Text Appearing Before Image:
ion of above two constitutes op-erating or performance characteristic. The open circuit characteristic of any magneto1 in-cludes flux distribution in the air gap and the e.m.f. gener-ated. The flux distribution wave of the machine of this typeis naturally a flat top consequently the e.m.f. wave is high-ly peaked form. Fig. 20, 21, and 22 are oscillograms of opencircuit e.m.f. waves of Splitdorf low-tension, Dixie high-tension, and Bosch high-tension respectively. Analysis ofSplitdorf low-tension e.m.f. wave is given in the tables 2-ato 2-d which shows e.m.f. wave contains appreciable harmonicsas high as 11th. The subsequent analyses show that 33rdharmonic has the maximum value of nearly .03 volts that issomewhere near one-third percent of the fundamental wave. The graph 3 shows approximate wave forms of e.m.f.and flux distribution at no load with the proper phase angledisplaced. The flux distribution wave is obtained from thefollowing; we have e = - Ua S**& =» - Z tc-f/o8or /0* r
