Abstract
Procedimiento para la medición del número de revoluciones (n) de una máquina de inducción (2), cuyo estator está conectado a través de un regulador de corriente alterna (4) controlable con disposiciones de válvulas (V1, V2, V3) a una red de tensión alterna (L1, L2, L3) mono o polifásica, caracterizado - porque el estator es separado de la red de tensión alterna (L1, L2, L3) durante al menos un intervalo de tiempo (t) predeterminado, que es menor que un semiperiodo (T) de la tensión de la red, a través del control de las disposiciones de válvula (V1, V2, V3), - porque en el intervalo de tiempo (t), que es menor que un semiperiodo, se mide la tensión inducida en el estator a través del movimiento giratorio del rotor y a partir de ello se determinan los componentes (Usx, Usy) del vector espacial (Us) de la tensión del estator, y - porque a partir de los valores de medición obtenidos de esta manera se determina la frecuencia de rotación del vector espacial (Us) de la tensión del estator y apartir de ello se deriva el número de revoluciones (n) de la máquina de inducción (2).
