Abstract

The external magnetic field of idling three-phase induction motors in electrical systems is investigated in the following cases: with no faults; with a turn-to-turn short-circuit in a stator phase; with rupture of a stator phase; and with static eccentricity. The field is modeled by the finite-element method on the basis of the Laplace equations and Ansoft Maxwell v.14 software.
