How to Build a Power Generator

by Lara Winston

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.

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.
