INGCO S-JS-R-JS6508 Jig Saw-Rotor

The INGCO S-JS-R-JS6508 Rotor is a crucial component in electric motors, generators, and alternators. Let’s delve into its features and workings:

1. Definition:
   • The rotor is the rotating part within an electromagnetic system of a motor, generator, or alternator.
   • Also known as the flywheel, rotating magnetic core, or simply the alternator.
   • In alternators, it includes permanent magnets that move relative to the iron plates of the stator, generating alternating current (AC).
   • The rotor utilizes existing motion for its function.
2. Construction and Working Principle:
   • In a three-phase induction motor, when AC is applied to the rotor, the stator windings create a rotary magnetic flux.
   • This flux generates a magnetic field in the air gap between the stator and the rotor, inducing a voltage across the rotor bars.
   • The rotor circuit can be shorted, allowing current flow in the conductors.
   • The interaction of the rotary flux and current generates a force, resulting in torque that starts the motor.
   • In an alternator, the rotor may have a wire coil enclosed in an iron core.
   • The field current (usually DC) flows through slip rings and brushes, creating a magnetic field with north and south poles.
   • The motor’s direction (clockwise or counterclockwise) is controlled by the magnets and fixed magnetic fields.
