Fault analysis of induction motors with broken bars or inter-turn short circuits needs accurate machine models to correctly identify and quantify the magnitude of the fault. Winding inductances and their derivatives are a key component of these models. In this paper a new, very easy and extremely fast method to compute them, based on the Magnetic Vector Potential (MVP), the Discrete Circular Convolution and the Fast Fourier Transform (FFT), is presented.

PL

Przedstawiono analizę uszkodzeń silnika indukcyjnego spowodowanych złamaniem prętu, lub zwarciem wewnętrznym. Oszacowano amplitudę wynikającą z uszkodzenia. Induktancja uzwojeń jest kluczowa w tym modelu. Zaproponowana metoda jest bardzo prosta i szybka. Zastosowano wektorowy potencjał magnetyczny oraz szybką transformatę Fouriera.
