This paper presents a fault diagnosis for opening phase in the stator of a synchronous permanent magnet motor (msip) using the finite element method (fem) in 2D. The analysis was based on the behavior of the responses of the motor variables in steady state under normal operation of the machine, as well as their behavior in transitional and post-failure state. This analysis is done with the aim of categorizing the type of fault according to the content of harmonics in the currents of the stator. Five diagnostic methods known in the literature were used to determine the type of fault just observing the content of harmonics in the stator currents. The diagnostic methods used were: 1-Fast Fourier Transform, 2-Geometric place of the Park Vector, 3-spectral density of energy, 4- Multiple Signal Classification and 5-Method of the Impedance of Reverse Sequence. The results found were consistent for the same fault.
