Which Parts Of An Electric Generator Are Connected?

An electric generator has several connected parts that work together to convert mechanical energy into electrical energy. Let’s break it down step by step:

Key Connected Parts in an Electric Generator:

1. Rotor (Armature or Field) and Shaft:

   • The rotor is the rotating part of the generator.
   • It is connected to a shaft, which is turned by an external mechanical force (like a turbine, engine, or hand crank).

2. Stator and Rotor (Magnetic Field Interaction):

   • The stator is the stationary part of the generator.
   • The rotor rotates inside or around the stator, creating a changing magnetic field.
   • This interaction induces an electric current in the stator windings.

3. Armature and Slip Rings/Commutator:

   • In AC generators, the armature is connected to slip rings, allowing continuous rotation while maintaining electrical contact.
   • In DC generators, the armature is connected to a commutator, which converts AC to DC by reversing current direction.

4. Windings and Output Terminals:

   • The generated current flows through coil windings inside the generator.
   • These windings are connected to output terminals, which provide electricity to external devices.

Practical Explanation:

Imagine turning a bicycle dynamo (a small generator).

• The wheel (like the shaft) turns the rotor, which interacts with the stator to generate electricity.
• This electricity is sent through wires (windings) to power a bulb (like the output terminals).
