AC Generator, Simple DIY project with Step by Step instructions

Introduction

AC generator discusses the conversion of mechanical energy (kinetic energy) into electrical energy by using magnetic induction and emf. It focuses on the working principles and components used in it.  The interchange of different energies and electricity generation by the process of induction can be completely explained by AC generator.

Material required:

For construction of Electric Generator you need following things and tools.

  1. Supper Glue (Elfi) 20 ml
  2. Paper Tape
  3. Iron Strips 2
  4. 1/5'" PVC Pipe
  5. 6" long Iron Nail
  6. LED's
  7. Copper Wire 30 to 34 gauge
  8. 4 Magnets
  9. 6'' wooden Piece

Tools:

  1. Iron saw
  2. Soldiering Iron
  3. Drill Machine
  4. Screwdriver
  5. pliers
  6. Roller

Steps of Construction

Making of Coil

  • Measure 2 ½ inch of iron strip and cut 10 equal parts of it.
  • Firmly hold and pile all parts together using paper tape in a way that there should be no space between strips.
  • Wound approximately 300 turns of copper wire around the bundle of strip vertically. Wrap paper tape around it so it will not get unwound.
  • We need two such coils to make an AC generator.

Making of Rotor

  • Take half inch diameter PVC pipe and cut a piece of 2 ½ inches
  • Stick 4 bar magnets on the piece of pipe with the help of super glue
  • Make sure the same pole of magnets must be in alternative manner. It will be in the order of North-South-North-South.
  • Check out the poles of magnets if they are aligned right by using another magnet.

Axle making

  • Make an axle using 6” long iron nail.
  • Leave half inch from the tail of nail and mark the length of magnetic rotor.
  • Wrap paper tape on the nail in a way that the magnetic rotor get fix on it.

Body of the Generator

  • Take 6×6" wooden piece and two pieces of PVC pipes (one is of 2" and the other is should be of 1").
  • Make vertical groove on the 1 inch PVC pipe.
  • Align it with 2 inches piece and make a hole in it.
  • Fix the axle through both PVC pipes and check if it is perfectly leveled.
  • Stick the PVC pipes on the wooden base with the help of super glue.
  • Make 2 more coils as previously discussed leaving both of their terminals outside the tape.
  • Cut 2 pieces of PVC pipes measuring half inch.
  • Join the pieces perpendicular to the axle (one at each side) at the base.
  • Fix coil on each of the PVC pipe.
  • Burn the coating of coils at the terminals using lighter.

Testing

  • Join the LED with the coil and rotate the nail, the LED will glow.
  • If both the coils are connected in series then LED will glow brighter.

Note: The construction of the generator can be seen in this video (language is Urdu). English subtitles have been added for international visitors.
