Lately, there is a need to come up with the latest and most efficient designs for any electrical appliance. The following is a design of a brushless DC fan running based on solar power, which is expected to run using a small 12 V battery and solar pv panel. A brushless DC motor (BLDC) is a synchronous motor powered by electrical communication system than mechanical commutator and brushes. This fan is implemented via Arduino UNO that generates the pulses and has an in-built analog comparator. The BLDC motor is enabled with a hall effect sensor that senses the pulses of the inverter and controls the fan. This assembly provides an alternative to conventional fan models with minimal energy use. .
