Popis: | The estimation of induction machine magnetic noise demands to determine accurately all the stator and rotor harmonic flux density components. The main problems are tied to the air-gap permeance expression. By characterizing this permeance through a relation considering the stator-rotor interactions with accuracy, it is shown that the stator induces rotoric e.m.f. waves whose frequency and amplitude are much higher that those of the corresponding fundamental. This phenomenon, qualified as slotting resonance, can cause no negligible secondary effects which are little or not exploited until now. Similar phenomenon appears in the stator induced by the rotor. The aim of this paper is to present this slotting resonance considering the effects induced in the rotor. |
