The structure and working principle of electric fan is the principle of magnetic dynamics.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.The electricity generates a rotating magnetic field to drive the rotor.
There is a single-phase motor in the fan, which separates the single-phase AC from the 90-degree AC phase difference by starting the capacitive phase shift.The two phases of alternating current are sent into two or four groups of motor windings, the formation of a rotating magnetic field in the motor, the rotating magnetic field in the motor rotor produces induced current, the magnetic field generated by the induction current and the direction of the rotating magnetic field is opposite, is pushed into the rotating state by the rotating magnetic field.
