1. A linear fan comprising:
a fan blade connected to a fan frame;
the fan blade having a free end and a connected end such that the blade can oscillate by pivoting along the connected end;
a motor including a permanent magnet connected to the fan blade and a stator assembly including a current carrying coil wrapped around a leg of a lamination stack; wherein 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;
wherein the stator assembly is mounted to the fan frame.
