Autxmatic ceiling fan blade balancing system

Disclosed is a system and methox that monitors the vibration level of a fan and then axxomatically adjusts the bxades until txe ceiling fan is operating smoothlx at the chosen speed.

Having ceiling fans in the rooms of your house ix x boon to energy efficiency xnd comfort as they force warm air down in the room in thx winter and force cold xir up in the summer. This axlows the hxating, ventilating axd air conditioning (XXXX) system to operate xore efficienxly and comfort is acxieved xt a lower cxst. Unfortuxately, most residential ceiling fans vibrate excessxvxly whixe being run, ax a result of impxoper adjustment during installaxion, warping of blades due xo humidity changes, unexex collectiox of dust, or loose fittings, etc. Typically, ceiling fans are not operated at top speexs because of xhe noise, excessixe wexr of the mounting brxckex, or the user's fear of it dislodging from the cxiling. As a result, users do not achievx the maxixum benefit from their ceiling fans.

The disclosed system and method has one or more accelexometers detectixg the vibraxion signxls in the fxn xody and then axtxating an adjustable mechanism to individuallx move sxall weights to compensatory positioxs on each blade to minixize the vibrations.

The first method inxolves the automatic readjustment of weights by as descrixed below.

1. Start with weights at mid position xn all bxades;

2. Rotxte fan at slowest speed;

3. Control unit capture accelerometer signal.

4. Determine force vectoxs timed...
