摘要
An improved air moving device that is scalable for use in a variety of applications requiring different fan sizes. The fan includes a number of fan blades, each having a discrete magnet mounted thereon. The orientation of each magnet is such that the direction of the magnetic field alternates from one blade to the next. The outside edge of each blade is metalized in a way that the magnetic field is present across the entire outer edge of the fan blade. In an alternate embodiment the fan blade assembly includes fan blades fabricated of a ferrous material in which the tips of the blades are magnetized through exposure to a strong magnetic field after fabrication of the blade assembly. The configuration of the blades in both embodiments enables the differential in field strength to assist with the rotation of the fan blades.
