ABSTRACT:
A spread adjusting motor for a ceiling fan with coils that distribute an even magnetic field for the fan rotor to eliminate the interval noises from the current. The main feature of the coils is that they use a skip or pass through winding process for the stator coils. The first step is to wind the starter coil continuously for two full slots and then skip two slots until a full round of winding upon the stator is completed. A similar skip winding process is used for each of the speed adjusting coils. Each of the speed coils is wound one full slot after skipping three slots until a full round of winding upon the stator is completed. When the skip winding process is done, the coils are evenly distributed around the stator.
