ABSTRACT:
A rotating assembly for electric fan in one embodiment includes a rotating member provided on an end of the rotating shaft for fastening the fan blades and including a protrusion extended oppositely the rotating shaft, and a coil formed around the protrusion; a stationary magnetic mechanism formed around an end of the protrusion and including at least one pair of magnetic poles on its inner surface spaced from the coil, and a counterweight formed externally; and a load radially extended from the protrusion, a plurality of light emitting elements, a circuit electrically connected to both the magnetic poles and the coil, and a controller electrically connected to the circuit for controlling an activation of the light emitting elements. Activating the electric fan will cause the light emitting elements to emit light. In another embodiment, negative ions are generated.
