How to make a mini hydroelectric power station on their own

To expand the production of alternative energy using a miniature hydroelectric power station, one of which was developed the American innovator. Such a plant can build all the who owns a home near the river. The author realized his project in three days.

He used a broken generator company Cummins Onan, which took the disks to the turbine wheel and the electrical generator he made from two brake rotors with a size of 28 cm Also used a wheel hub from an old Dodge. The turbine blades are made of 10-inch steel pipe, cut into four parts.





Further, the designer has produced the template, twelve inch wheels, which were labeled with the necessary holes, and place for the blades in the amount of 16 pieces.





Drilling must be done very precisely – depends on the efficiency of the entire installation.





After drilling the holes, the discs were connected by steel rods, with a length of 25 cm.





The obtained product was made a hole of 10 cm to facilitate the mounting of the electric generator in order to allow better access.





To enhance the tidal flow of water to the turbine was connected to a special nozzle into the pipe, made of bent sheet metal.





The result has its own power tube with the original nozzle was fixed at an angle of 45 degrees, and the turbine itself pre-installed on the bushing. This approach allowed the designer to make adjustment. Installed pipe can move in all four directions, and the turbine and the generator can only deviate back and forth.





Generator American designer used the following approach: from the wire was manufactured stator, which has 9 identical rings, each of which was tightly wound 125 turns.





Also from the stator was allocated 6 cores, and the stator is filled epoxy compound.





The rotor has 12 magnets placed at the edges.









The connection between the rotor and stator was performed using a mixture of polyester and fiberglass.





Created generator fixed on one side of the turbine.





With the free side of the electric generator attached to the transducer, which is placed in a special housing made of aluminium. It converts three phase AC into DC. The capacity of the plant amounted to 12.5 W at 38 rpm.









For operation used the stream that flowed near the house of the designer.





From this stream the water is diverted and supplied to the turbine.





After selecting the angle of the average turbine rotation speed 110 rpm.





As a result, the turbine supplies a current of 2 amps (at 12V voltage). published
