How Do You Build A Generator Using An Electric Motor?
Your permanent magnet electric motor can be used as a generator. All that needs to be done is to apply an external power source to spin the shaft of any permanent magnet electric motor and your motor becomes a generator. Your electric motor generator will need to be spun slightly faster than a unit specifically designed as a generator, but there is little difference between a permanent magnet electric motor and a generator. Cut one of your 6-foot 2 by 4s in half so you have two pieces each that are 3 feet long. Cut two pieces from your other 6-foot 2 by 4 that are 2 feet 9 inches long each. Set the cut 2 by 4s on edge and arrange then so they form a square 3-foot by 3-foot frame. Using two 2 1/2-inch wood screws at each corner secure your frame. Lay the 3-foot X 3-foot sheet of 3/4 plywood on top of the frame and screw 3 1 1/2-inch wood screws along each edge. You now have a very sturdy platform on which to mount your permanent magnet electric motor and your small gasoline engine. Set
