Abstract
A modular ceiling fan assembly and system is disclosed in which the functioning components are standardized, including standardized connections for their assembly, and multiple components are provided with a plurality of alternate parts for assembly into a variety of uniquely differentiating configurations, styles and appearance without substantially increasing the cost to the manufacturer. The motor platform, including the motor, shafts, switch housing and electrical components and wiring, are standardized into a single configuration, and the holes for mounting the fan blades on the lower surface and/or upper surface of the rotor have a standardized size and spacing. A modular motor housing is formed from multiple horizontal sections, preferably two or three, with a standardized height to accommodate the common single motor platform. The various sections of the modular motor housing are selected in order to produce a variety of uniquely different appearances. Alternative modular blade attachments, including blade ring and paddle assemblies, blade ramps and blade irons, with and without blade rings, are configured to be mounted in the standardized mounting holes of the rotor. These…
