An AC (alternating current) motor is a type of electric motor that operates on alternating current, which means the direction of the electrical current periodically reverses. AC motors are commonly used in various applications, from industrial machinery to household appliances. There are two main types of AC motors: synchronous and asynchronous (induction) motors. I'll explain how an asynchronous AC induction motor works, as it's one of the most common types.
Basic Components of an AC Induction Motor:
Stator: The stator is the stationary part of the motor and consists of a set of coils that are wound around a laminated iron core. These coils are connected to the AC power supply.
Rotor: The rotor is the rotating part of the motor. It is also made up of a laminated iron core and can have conductive bars or coils embedded within it.
Working Principle:
Induction: When AC voltage is applied to the stator coils, it creates a rotating magnetic field. This rotating magnetic field induces voltage and current in the rotor due to electromagnetic induction.
Eddy Currents: The rotor's conductive elements (bars or coils) are exposed to the changing magnetic field produced by the stator. This changing magnetic field induces eddy currents in the rotor's conductive elements.
Rotor's Magnetic Field: The eddy
