Abstract :
Two structures constitute an electric machine, one is the electric winding and the other is the magnetic circuit, which are geometrically linked, the mutual induction being the expression of it. A failure that provokes electromagnetic irregularities, modifies the structures or the relationship that characterize a healthy machine. This paper proposes to measure and analyze the spectrum of the leakage flux on the stator on the outside of the machine and its instantaneous reactive power showing the modifications due to the failure. This method is noninvasive and, the same time, allows to analysis of the main flux in the machine without internal probe coil. In the analysis the vector of the structure of winding concept was introduced.
