Design and Development of Interactive LED Display for Fan Applications

This paper describes how to apply the external driving motor structure to trigger the inner motor structure of the impeller, and self-generate DC power through the conversion of electromagnetic energy, which has the advantages of simple structure, reduced fan thickness and no need of another extra power to provide for the LED display circuit. Moreover, with the contactless capacitive touchpad, to demonstrate the new interactive interface design, showing the dynamic text and graphics information, etc. The purpose is to integrate new motor structure, supplemented by the relevant LED and sensor applications to enhance the added value of the traditional cooling fan products, and diversified applications with creative digital content, can be used as a reference for industries upgrading and product design.
