摘要：

This paper, after a detailed literature analysis, presents new results which show the actual possibility to detect inter-turn short-circuits in low voltage induction motors by means of measurements of the stray flux around the motor. With respect to the literature, some novelties are introduced: the use of different flux probes in different positions around the machine and the statistical evaluation of the experimental results. The effectiveness of the flux as diagnostic indicator has been compared to the motor current signal analysis (MCSA).
