    Abstract: A direct drive ceiling fan is described that includes at least one blade and a permanent magnet motor (e.g., PMSM) as a driving source. The permanent magnet motor includes a stator with a 45 to 90 slot construction and multiple stator winding coils and the rotor assembly includes a permanent magnet that has from 50 to 80 magnetic poles. The coils are wound according to a symmetric winding pattern that is selected based on the numbers of slots and poles used in the motor. The resulting motor produces near zero to zero radial forces (Fx and Fy) during operation of the fan.
