Introduction Of Ceiling Fan Motor:
The ceiling fan motor consists of two main components: the stator and the rotor. The stator is a stationary part of the motor and contains a set of electromagnetic coils. The rotor, on the other hand, is the rotating part of the motor and is connected to the fan blades.
When the power is applied, an electric current flows through the coils in the stator, generating a magnetic field. The interaction between the magnetic field and the rotor creates a force that causes the rotor to rotate.Ceiling fan motors typically use a type of motor called an induction motor. Induction motors do not require a commutator for switching the current flow in the stator coils. Instead, they rely on the principle of electromagnetic induction.
