PRIOR RELATED APPLICATIONS [0001]Not applicable. FEDERALLY SPONSORED RESEARCH STATEMENT [0002]Not applicable. REFERENCE TO MICROFICHE APPENDIX [0003]Not applicable. FIELD OF THE INVENTION [0004]The invention is directed to a ceiling fan. BACKGROUND OF THE INVENTION [0005]A typical ceiling fan includes a down rod assembly suspended from the ceiling with a motor shaft connected to a lower portion of the down rod assembly. A motor body rotates about the motor shaft. Blade mounting arms, also referred to as blade irons, are connected to the motor body and extend out of an opening of the motor housing or below the motor housing. [0006]Motors used in the art tend to be proximate to the fan blades. Typically, fan blades are connected to the motor via blade irons. However, motors tend to be cumbersome and unattractive causing manufacturers to encase or mask the motor within a housing. Unfortunately, the bulk of the motor limits the aesthetics of the ceiling fan housing. Furthermore, when the downrod assembly positions the ceiling fan a distance from the ceiling, horizontal movement of the ceiling fan may occur during operation. SUMMARY OF THE INVENTION [0007]Some embodiments of the invention provide a ceiling fan comprising a motor assembly, a shaft having a first end and a second end, and a hub having a fan blade assembly wherein the first end of the shaft is coaxially coupled to the motor assembly and the second end of the shaft is coaxially coupled to the fan blade assembly, and wherein the motor assembly rotates the shaft and the shaft rotates the fan blade assembly. In such embodiments of the invention, the motor assembly and fan blade assembly may be substantially remote to each other. In some embodiments of the invention, the shaft is coupled to the motor assembly via a first attachment mechanism and the shaft is coupled to the fan blade assembly via a second attachment mechanism. In yet other embodiments of the invention, the first attachment mechanism comprises a coupling interface. In yet other embodiments of the invention, the second attachment mechanism comprises a mechanical fastener. [0008]Some embodiments of the invention provide a system for supporting a ceiling fan assembly having a motor, a motor housing, a fan blade assembly and a downrod, the system comprising coupling means for coupling the ceiling fan assembly to a support surface and supporting at least some of the weight of the ceiling fan assembly, and stability means for reducing the amount of horizontal movement of the ceiling fan assembly. In some of such embodiments, the stability means comprise a plurality of cables. In some embodiments of the invention, the cables extend from the coupling means to an upper portion of a hub which is coupled to the fan blade assembly. In yet other embodiments of the invention, the upper portion of the hub is static during the operation of the ceiling fan. In yet other embodiments of the invention, the cables comprise a tensioning mechanism which adjusts to secure the ceiling fan assembly to the coupling means and the upper portion of the hub. [0009]Some embodiments of the invention provide a system for attaching a light kit to a ceiling fan assembly having a motor, a motor housing, a fan blade assembly and a downrod, and comprising an inner downrod, an outer downrod, and a sleeve wherein the sleeve and the inner downrod are stationary during operation, and wherein the outer downrod is coupled to the fan blade assembly and rotates with the motor, and the light kit is coupled to the inner downrod. [0010]In yet other embodiments of the invention a system for minimizing horizontal movement of a ceiling fan assembly having a motor and a fan blade assembly, the system comprising a support ring, one or more cables, and a hub wherein the support ring couples the ceiling fan assembly to the ceiling, and wherein the cables couple the support ring to the hub is provided. In some such embodiments the cable further comprises a tensioning mechanism for tightening or lessening the tension in the cables. In some embodiments of the invention, the hub is further coupled to the fan blade assembly and the hub is stationary during operation and the fan blade assembly rotates with the motor during operation. BRIEF DESCRIPTION OF THE DRAWINGS [0011]The accompanying drawings, which are incorporated in and constitute a part of this specification, exemplify the invention and together with the description, serve to explain the principles of the invention. [0012]FIG. 1 shows a side elevation view of an embodiment of the invention. [0013]FIG. 2 shows an enlarged cut-away view of the embodiment in FIG. 1. DESCRIPTION OF EMBODIMENTS OF THE INVENTION [0014]Reference will now be made in detail to embodiments of the invention, an example of which is illustrated in the accompanying drawings. [0015]Referring to FIGS. 1 and 2 showing an embodiment of the invention, a ceiling fan 10 generally includes a mounting assembly 12, a motor assembly 14, a downrod assembly 16, a hub assembly 18, and a light kit 20. In a preferred embodiment, the motor assembly 14 and the hub assembly 18 are coaxially coupled via the downrod assembly 16. [0016]The ceiling fan 10 is connected to the ceiling via the mounting assembly 12. The mounting assembly 12 connects to the ceiling, or other support surface, on one side and couples to the motor assembly 14 on the other side. Electrical wires for powering and controlling the ceiling fan 10 pass through the mounting assembly 12 to the motor assembly 14. The mounting assembly 12 may be an interface plate that connects to a junction box in the ceiling. The interface plate also supports some of the weight of the ceiling fan 10. Although an interface plate is illustrated as connecting the ceiling fan 10 to the ceiling, other commonly known mechanical methods of coupling the ceiling fan 10 to the ceiling or other support surface are contemplated as being included in the present invention, and include, without limitation, mechanical fasteners, and the like.
