Abstract

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