The motor is controlled by a PFC-based control mod ule, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. N4 The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades fom falling when a ft blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.
