Abstract

See full text

A cantilever fan including a blade and a blade permanent magnet. The blade is clamped at one end to a base and has a distal end which is free to oscillate with distal end having the largest swept displacement of any portion of the blade. The blade extends from the clamped end to the distal end. The blade permanent magnet is attached only to the blade at a point along the blade's length and is free to move with the blade. The fan includes a stationary permanent magnet attached only to the base. The respective locations and relative orientation of the blade permanent magnet and stationary magnet result in a repulsive magnetic force between the blade permanent magnet and stationary magnet. The fan is configured so that the repulsive force increases as the blade's deflection brings the blade permanent magnet closer to the stationary magnet.
