Finite Elements Method is a contemporary numerical method for determination of distribution ofudelectromagnetic fields inside different objects. In this paper three different induction motors will beudanalyzed : Solid Salient Poles Synchronous Motor, product of company MAWDSLEY, Single PhaseudShaded Pole Motor, product of company Micron-Tech and Induction Squirrel Cage Motor, product ofudcompany Koncar. In all analyzed motors distribution of electromagnetic field and magnetic fluxuddensity are calculated using two different approaches: magneto-static at zero herz frequency andudmagneto-dynamic at fifty herz frequency. Further on, calculation of different motor parameters such asudmagnetic flux density distribution in motor air gap at different operating regimes is performed andudadequate conclusion are derived.udKeywords: Finite Elements Method, Magnetic Fields Calculation, Induction Motors
