How to Build a Power Generator

Save

Generators can be used to power every day appliances, and they are also used at carnivals and outdoor events. Power generators are also very useful as a source of power in emergencies. There are various types of generators; however, the most common type is one powered by electricity. It is possible to make your own generator using a magnet electrical motor.

Things You'll Need

  • Permanent magnet electric motor
  • Small gasoline engine
  • Fan belt
  • Two 6-inch diameter pulleys
  • Two 6-foot 2-by-4s
  • Drill
  • Allen wrench
  • 3-foot by 3-foot sheet of 3/4-inch plywood
  • Jigsaw
  • Eight 2.5-inch wood screws
  • Twelve 1.5-inch wood screws
  • 1.5-inch bolts, nuts and lock washers
  • Pencil
  • Cut two 6-foot 2 by 4s in half. Put the four 3-foot pieces on the floor or any smooth surface. Make them into a square.

  • Fasten the corners of the square using the 2.5-inch screws. Use two screws for each corner. Put a 3-foot by 3-foot piece of plywood onto the square. Fasten the plywood to the square with three 1.5-inch wood screws.

  • Put the gasoline motor engine on top of the plywood square. Make four holes in the square using a drill. Use 1.5-inch bolts, washers and nuts to secure the engine.

  • Place a pulley on the edge or the shaft of the engine with an Allen wrench. Put another pulley on the permanent magnet motor.

  • Put a fan belt next to the pulleys. The fan belt will help the shaft of the electric motor spin while the engine is running.

  • Pull the electric motor away from the gasoline engine. The pulleys should be positioned in a straight line. The fan belt should be pulled taut between the engine and motor.

  • Mark the place where the motor extended to. Use the drill to create holes for the motor. Use a jigsaw to make the holes slightly longer. They should end up looking like slots rather than holes. Fix the electric motor to the plywood with four 1.5-inch bolts, washers and nuts. Use the wrench to fasten the nuts and washers.

  • Check to see if the generator is working. Start the engine and check its efficiency.

Tips & Warnings

  • Be very careful when using electrical equipment to avoid serious injury. Keep away from pets and children.
