摘要：
A ram air fan control system includes a ram air fan motor, the ram air fan motor being a pole-change induction motor with at least two pole-count configurations, a ram air fan contactor in operative communication with a first pole-count configuration of the ram air fan motor over a ram air fan conductor bus, a ram air fan power controller in operative communication with the ram air fan contactor, a common contactor in operative communication a second pole-count configuration of the ram air fan motor over a common conductor bus, the common conductor bus being separate and electrically isolated from the ram air fan conductor bus, and a common power controller in operative communication with the common contactor.
