Zusammenfassung:	A linear fan including a fan blade attached a fan frame by a wire spring having a first end attached to the fan blade and a second end attached to the fan frame. The fan blade includes a free end such that the blade oscillates by pivoting on the wire spring. The the wire spring flexes to enable the fan blade to oscillate. The fan includes a motor for driving the oscillation of the fan blade. The motor includes an armature or permanent magnet connected to the fan blade and a stator assembly connected to the fan frame. The stator assembly includes a current carrying coil wrapped around a leg of a stator core. The motor is controlled to vary the direction of the current being carried in the coil to thereby change the direction of the magnetic field created by the stator assembly and cause the fan blade to oscillate.
