Abstract

La presente invención se refiere a un método para detectar y corregir el desbalance de carga en un aparato doméstico tal como una máquina lavadora, dicho aparato teniendo un ciclo operacional dividido en por lo menos una porción de distribución de carga en la que la carga se distribuye con respecto a un eje y una porción de postdistribución en la que la carga gira alrededor del eje de rotación a una velocidad relativamente alta, dicha carga estando impulsada por un motor de inducción accionado por una impulsión por inversor de corriente directa, dicho método caracterizado porque comprende: energizar el motor a una frecuencia predeterminada para impulsar la carga a una velocidad nominal predeterminada, en un punto predeterminado en la porción de distribución de carga del ciclo operacional del aparato; examinar la ondulación en la corriente directa mediante la impulsión por inversor mientras que el motor se energiza a la frecuencia predeterminada y comparando dicha ondulación con una referencia predeterminada; e iniciar la porción de postdistribución del ciclo operacional únicamente si la ondulación cae por debajo de la referencia predeterminada.
