The main types of motors in ceiling fans are AC or DC motors. The AC (alternative current) or DC (direct current) refers to the electrical current the motor uses. Homes in Australia typically use AC power, however, DC ceiling fans can also connect to Australian wiring.
DC Fans have an internal adaptor that converts the AC power into DC power to operate the fan. AC fans are the most conventional type of fan and have been around for a while. AC fans tend to be relatively more cost-effective to buy than DC fans as they have simpler production and are more conventional in the market. DC fans are highly energy efficient, the motors consume up to 58% less energy than conventional motors and are more cost-effective to run.
