  • Ceiling fan system
    Patent number: 11009033
    Abstract: A fan system includes a hub configured to rotate and a plurality of fan blades mounted to the hub. A motor is operable to rotate the hub. A motor controller in communication with the motor is configured to control operation of the motor. A control panel in communication with the motor controller has an input port for receiving data relating to operation of the fan system.

  • CEILING FAN SYSTEM WITH BRUSHLESS MOTOR
    Publication number: 20170101999
    Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. 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 from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.
