Alternating Current (AC): AC motors use electricity that changes direction periodically, typically at a frequency of 50 or 60 Hertz. This variation causes the magnetic field in the motor to continually change, creating rotational motion.
-
Stator and Rotor:
– The stator is the stationary part of the motor. It consists of coils of wire that generate a magnetic field when AC flows through them.
– The rotor is the rotating part inside the stator. It can be a simple metal cylinder or a series of conductors. The rotor responds to the changing magnetic field, leading to rotation. -
Electromagnetic Induction: This principle explains how the changing magnetic field produced by the stator induces current in the rotor. According to Faraday’s Law of Electromagnetic Induction, a changing magnetic field creates an electric current in a conductor. This current then interacts with the magnetic field, leading to motion.
-
Slip: Slip is the difference between the speed of the stator’s magnetic field and the actual speed of the rotor. It is essential for the operation of an induction motor, which is a common type of AC motor. Slip allows the rotor to catch up with the stator’s magnetic field at a lower speed necessary for the motor to generate torque.
