Abstract
This pager presents a new design of a ceiling fan. This new fan features hi gh overall system efficiency. An axial-flux brushless DC machine (BDCM) wit h high energy-efficiency is used to drive newly designed, high efficiency b lades, incorporated into a complete new overall design. In addition, a conv entional ceiling fan has been retrofitted with a high efficiency BDCM and a ssociated drive electronics. Performance testing has been undertaken. A det ailed study of a range of commercially available conventional ceiling fans has been undertaken. Comparative results of measurements of electrical inpu t power, mechanical power on the shaft, approximated power in the airflow, and calculated efficiencies are presented.
