A fan is a powered machine used to create flow within a fluid, typically a gas such as air. A fan consists of a rotating arrangement of vanes or blades which act on the air. The rotating assembly of blades and hub is known as an impeller, a rotor, or a runner. Usually, it is contained within some form of housing or case. This may direct the airflow or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, internal combustion engines, and solar power.
Electric fans circulate air by using electricity to spin a rotor shaft attached to the fan blades. Wires wrapped around magnets inside the fan motor's housing carry electric current, turning the magnets into powerful electromagnets.
India electric fans market is projected to surpass $ 2 billion by 2023. Growing presence of organized retail outlets, increasing spending power and rising preference for online sales platform and modular homes is expected to boost demand for electric fans in India over the coming years.
