About DC Motor Ceiling Fans: Unlike AC motors that use electricity to create a magnetic field, DC motors have their own built-in permanent magnets, so they use 3 to 5 times less electricity. DC motors that are capable of running off standard household AC current have been around for quite some time, so you would think that ceiling fans manufacturers would have started using them a long time ago. However, there is a lot more to making a DC motor work with AC current than simply inserting it into a fan that normally uses an AC motor. There are sophisticated built-in electronics that are necessary in order to allow a brushless DC motor operate from typical household AC electricity. Until recently, these electronics were far too costly, so it did not make sense to use them in ceiling fans. But things have changed. Read More about DC Motor Ceiling Fans Here!
