Abstract: Disclosed is a high volume low speed (HVLS) fan that is designed to circulate air in large buildings for cooling, heating, and ventilation. A fan with a diameter between 8 to 24 feet consisting of a plurality of blades, with each in the shape of a tapered airfoil, is driven by a direct drive transverse flux electric motor to produce a very large slowly moving column of air. The HVLS system preferably includes motion and angular shutdown, voltage recognition, blade size recognition and data logging for recording the last 100 or so hours of operation to facilitate warranty applicability and assist in trouble shooting as well as software updates and programming via Bluetooth and internet keypad.
