    The purpose of this technical project is the design and construction of a radial flow generator of permanent neodymium magnets with outgoing pole stator, with which electric power was generated from the use of permanent neodymium magnets subject to the stator, which they are used to maintain a permanent magnetic field and with a winding rotor. For the elaboration of this project the hydraulic energy of the waterfall “El Silencio” located in the parish Ulba was used in the song Baños de Agua Santa with a waterfall of 30m and two turbo-pumps Pelton and Michell-Banki in order to identify the configuration that provides the greatest energy delivery. Two winding rotors were built, one of A36 and the other of silicon steel M19, maintaining similar configurations in the type of winding, however, the A36 rotor had a higher magnetic field density due to its high carbon content. This caused that the flow required to overcome the inertia of the rotor is greater, in addition, its temperature increased from 40 to 120 ° C in the winding limiting its operation. In the tests, the data of voltage, amperage, flow rate and rpm were collected, which were tabulated and plotted. In interpreting the graphs, it was determined that the Michell-Banki turbo-pump had better results than the Pelton turbo-pump. Achieving a voltage between 80 – 110 V with a resistance of 20 ohm and a maximum amperage of 4.57 A, the flow required for its operation was between the range of 50 to 150 m3/h. The application of this system in conjunction with the turbo-pump Michell-Banki and generator of permanent magnets of neodymium with stator of protruding poles and rotor of silicon steel M19 could be applied to a house to which the electric service is limited by the wiring public and the pumping of vital fluid is required.
