Abstract

The present invention relates to a system for controlling the motion of fan blades, enabling them to come to rest in a precise alignment with a polygonal stationary central display, thereby ensuring that the fan blades assume a consistent and predetermined orientation when stationary, said system includes a metal down rod configured to hang the fan from the ceiling; a stator fixed inside the rotor housing with a plurality of coils to generate an electromagnetic field, wherein the plurality of coils include a first set of coils and a second set of coils, wherein the first set of coils act as electromagnets; a display screen mounted over the stator or shaft bottom end to remain stationary; a processing unit configured to detect the rotation per minute (RPM) of the fan blades.
