Özet

"Tesla's Egg of Columbus" is the name given to the experiment conducted in 1893 by Nikola Tesla that proved the existence of rotating magnetic field produced by two-phase AC winding. In this study, a generalized mathematical magnetic field model for m-phase "Tesla's Egg of Columbus"is presented in detail, and a novel 3-phase model of "Tesla's Egg of Columbus" is designed analytically by means of generalized expressions. Electrical and geometric quantities are calculated, and the system is analyzed by finite element analysis (FEA).The designed system is manufactured and tested for rated current and for constant and variable frequency with eggs made of different materials. Optimized frequency for materials and geometries are obtained and compared.
