DC fans have a variable, uneven flow. In contrast, AC fans change direction 50 times a second in order to provide a constant flow. But when energy-efficiency costs come into play, more designers are opting for the EC fans rather than familiar AC and DC versions. DC technology has become much more sophisticated in recent years, and it can now be applied to both residential and industrial ceiling fans. DC fans have motors that rely on permanent, built-in magnets in order to attract and repel a rotor around an axis joined with inverters. DC technology is much newer than AC technology. The permanent magnets are mounted inside the rotor with the fan impeller attached. In EC fans’ permanent magnet motors run on high voltage direct current (DC) electricity with built in AC to DC conversion which allows them to run direct from single phase or three phase mains supplies. There are several suppliers of AC, DC as well as motors.  Demand for construction industry in developed nations, and encourag
