Abstract

Un método para hacer funcionar un motor de inducción eléctrica con un accionamiento de velocidad variable que incluye determinar un nivel de tensión en un bus de continua correspondiente al accionamiento, y medir una primera magnitud del flujo magnético de un estator del motor eléctrico que funciona normalmente, determinando un nivel de flujo normal. El método incluye inhabilitar una primera salida al accionamiento cuando la tensión del bus de continua es inferior a un primer nivel de umbral. El método incluye medir una señal de realimentación del flujo magnético que tiene una fase y una segunda magnitud, estimar la velocidad del motor eléctrico, y configurar una segunda señal de salida correspondiente al accionamiento cuando la tensión del bus de continua es superior a un segundo nivel de umbral. La segunda señal de salida coincide con una señal de la segunda magnitud y una fase del flujo magnético. El método incluye permitir que la salida del accionamiento encienda nuevamente el motor eléctrico cuando el flujo magnético es superior a un tercer valor de umbral.A method of operating an electric induction motor with a variable speed drive including determining a voltage level on a DC bus corresponding to the drive, and measuring a first magnitude of magnetic flux from a normally operating electric motor stator, determining a normal flow level. The method includes disabling a first output to the drive when the DC bus voltage is below a first threshold level. The method includes measuring a magnetic flux feedback signal having a phase and a second magnitude, estimating the speed of the electric motor, and setting a second output signal corresponding to the drive when the DC bus voltage is higher than a second level. threshold. The second output signal coincides with a signal of the second magnitude and a phase of the magnetic flux. The method includes allowing the output of the drive to turn the electric motor back on when the magnetic flux is greater than a third threshold value.
