Cálculo del espectro de frecuencias en FMOD

Agustí Melchor, Manuel (2023-05-31)

El sonido puede ser definido como una onda de presión que provoca la vibración de las moléculas en un medio, como puede ser el aire, y que cambia con el tiempo, por lo que se habla del sonido como un "frente de ondas". En ...
Cost-Effective Reduced Envelope of the Stator Current via Synchronous Sampling for the Diagnosis of Rotor Asymmetries in Induction Machines Working at Very Low Slip

Burriel-Valencia, Jordi; Puche-Panadero, Rubén; Martinez-Roman, Javier; Sapena-Bano, Angel; Pineda-Sanchez, Manuel (MDPI AG, 2019-08-20)

[EN] Fault diagnosis of rotor asymmetries of induction machines (IMs) using the stator current relies on the detection of the characteristic signatures of the fault harmonics in the current spectrum. In some scenarios, ...
Detection of Broken Outer-Cage Bars for Double-Cage Induction Motors Under the Startup Transient

Antonino-Daviu, J.; Riera-Guasp, Martín; Pons Llinares, Joan; Park, Jongbin; Lee, Sang Bin; Yoo, Jiyoon; Kral, Christian (Institute of Electrical and Electronics Engineers, 2012)

[EN] Unlike single-cage rotor fault detection, fast Fourier transform (FFT)-based steady-state spectrum analysis techniques can fail to detect outer-cage faults in double-cage induction motors due to the small outer-cage ...
