I made this for my science project on renewable energy. Its a perpetual motion machine known as an overbalanced wheel... Bhāskara's wheel to be exact. It took a ton of work to get just right; I had to clean and grease the bearings several times, water wasn't heavy enough so we had to dissolve a TON of salt in the water to increase the weight, and then we had to tape coins to the wheel in several spots to get the wheel as perfectly balanced as possible.
CR- MOTOR - the engine, which bases its operation on the magnetic repulsion and the increase of the magnetic field by concentration of the lines of force. It is composed of rotating discs, which can rotate in the same direction, or in the opposite direction (counter-revolution). The discs contain permanent magnets (neodymium) that follow the rotating magnetic field, generated by the stator. It has a variable number of coils according to the revolutions or power that you wish to obtain. The rotation control is carried out by means of a magnetic field detector (hall) with electronic position control.
