This paper presents the experimental results obtained by implementing two different methods to simulate stator short circuits in laboratory for induction motors. In order to diagnose this fault, the measurements of one phase stator current and of the stray flux gathered in different positions around the motor have been statistically processed. The novelty introduced by the use of two different techniques to simulate the same fault consists in a more robust identification of the diagnostic indicators that could be employed in the industry for the condition monitoring of the low voltage induction motors.

Abstract
This paper presents the experimental results obtained by implementing two different methods to simulate stator short circuits in laboratory for induction motors. In order to diagnose this fault, the measurements of one phase stator current and of the stray flux gathered in different positions around the motor have been statistically processed. The novelty introduced by the use of two different techniques to simulate the same fault consists in a more robust identification of the diagnostic indicators that could be employed in the industry for the condition monitoring of the low voltage induction motors.File in questo prodotto:
