Despite the emergence of new types of electric machines, the squirrel-cage induction motor remains the dominant one. A motor failure can result in large lost revenues. One of types of faults that can occur in these motors is airgap eccentricity. This paper presents results, based on a Finite Element Analysis. It is shown that static eccentricity leads to a non-uniform temperature distribution and contributes to the rise of the highest temperature spot in the motor, hence potentially shortening the lifespan of the stator insulation system.

PL

Klatkowy silnik indukcyjny wciąż dominuje wśród maszyn elektrycznych. Jednym z typowych uszkodzeń tego silnika jest ekscentryczność szczeliny powietrznej. Przeprowadzono analizę tego zjawiska wykorzystując metodę elementu skończonego. Statyczna ekscentryczność powoduje nierównomierny rozkład temperatury.
