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 ...
[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, ...
