Abstract

Sistema de frenado dinámico con control de velocidad para una cabina de ascensor. Se presenta un sistema de frenado de ascensor de un sistema de ascensor que tiene una cabina de ascensor. El sistema de frenado incluye un motor que tiene un eje acoplado a la cabina de ascensor, generando el motor potencia CA en respuesta al movimiento de la cabina. Un primer circuito rectificador que tiene una primera entrada CA y una primera salida CC está conectado eléctricamente al motor en la primera entrada CA. Un circuito de frenado que tiene un elemento resistivo y un dispositivo conmutador está conectado en serie a través de la primera salida CC. El dispositivo conmutador pone en derivación el elemento resistivo a través de la salida CC en respuesta a una condición de fallo para frenar dinámicamente la cabina de ascensor. Ventajosamente, esto ralentiza la velocidad de la cabina durante una operación de movimiento que la condición de fallo hace necesaria, permitiendo por ello el movimiento de pasajeros a cualquier nivel debajo o encima de la parada, dependiendo de una condición de desequilibrio de la cabina y un contrapeso. En una realización alternativa, el elemento resistivo incluye una resistencia variable. El sistema de frenado de ascensor puede incluir además un sensor para proporcionar una señal detectada indicativa de la velocidad de la cabina, donde el valor de la resistencia variable se varia en base a la señal detectada. Esto proporciona ventajosamente la regulación de la velocidad de la cabina.
