How to Build a Permanent Magnet Wind Generator With Stator Epoxy

Save money and the environment by making a wind generator.

If you want to make a wind generator, an old treadmill or printer comes in handy. Both of those items use permanent magnet motors, which convert wind energy into electricity. Wind generators channel wind to produce electricity to be used to power appliances or other electrical items. Make the wind generator without welding or nails by using stator epoxy. Stator epoxy is used for engines and stators because of its resistance to heat.

4-inch PVC pipe, length of 36 inches
Hand saw
1-inch plywood sheet
Jig saw
Power drill
1/2-inch drill bit
Stator epoxy
Brush
Permanent magnet motor

Instructions

- 1
  
  Cut a 4-inch PVC pipe to a length of 18 inches, using a hand saw. Position the PVC pipe vertically and cut the pipe in half. The half pipe is a fan blade. Repeat until you make four fan blades.
- 2
  
  Cut a 1-inch plywood sheet into a circle with a diameter of 4 inches, using a jig saw. The circle is the rotor. Drill a 1/2-inch indention into the center of the circle, using a power drill and 1/2-inch drill bit. Drill halfway into the rotor.
- 3
  
  Position the ends of the fan blades onto the rotor. Space the fan blades equally. Brush stator epoxy on the ends of the fan blades and rotor. Let the epoxy dry for one hour.
- 4
  
  Insert turbine rod of the permanent magnet motor into the indention in the rotor. Brush stator epoxy into the hole and on the turbine rod. Let the epoxy dry for one hour.
- 5
  
  Cut a 2-by-2 inch wooden plank to a length of 10 inches, using a hand saw. The plank is used to hold the motor, rotor and fan blades.
- 6
  
  Brush epoxy on the bottom of the motor and place the motor at the end of the rod.
- 7
  
  Cut a 1-inch plywood sheet to the dimensions of 5-by-5 inches, using a hand saw. The plywood sheet is the wind vane. Attach the wind vane to the end of the plank, using epoxy. The wind vane should be on the opposite side from the rotor. Let the epoxy dry for one hour.
- 8
  
  Drill a 1-inch hole in the bottom of the plank, using a power drill and 1-inch drill bit. The hole is the plank hole.
- 9
  
  Cut a wooden rod with a diameter of 1 inch to the length of 4 feet, using a hand saw. The rod is the tower.
- 10
  
  Insert one end of the tower into the center hole of a 20-pound free weight. The free weight supports the weight of the wind mill. Insert the other end of the tower into plank hole.
- 11
  
  Strip 1/2-inch both ends of an electrical wire, using a wire stripper. Twist the end of the electrical wire with the positive output of the magnet motor. Twist the other end of the wire with the positive input of a rechargeable battery. Cover the exposed wires, using electrical tape. Repeat the Step for the negative wire.
