Sell cheap ceiling-fan motor，The main components of the electric fan are: AC motor.Its working principle is: the current coil in the magnetic field force and rotation.The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and because of the resistance of the coil, it is inevitable that a part of the electric energy will be converted into internal energy.When the fan works, because there is a current through the coil of the fan, the wire is resistant, so it will inevitably produce heat and release heat outwards, so the temperature will rise.But why do people feel cool because there is a lot of sweat on the body surface, when the fan works, the indoor air will flow up, so it can promote the rapid evaporation of sweat, combined with "evaporation needs to absorb a lot of heat
