APPLIED RESEARCH REGARDING THE PROJECTION OF A SUBMERSIBLE ELECTRIC GENERATOR

The paper presents a new model of a perfect watertight submersible electric generator, tightness which is due to a pair of simerings directly connected to the generator’s shaft, in which the impulse is carried out by means of permanent magnets from rare grounds mounted on the electrical machine’s rotor with the help of epoxy resins. Due to the total tightness of the generator, the rolling bearings (ball bearings) were used, increasing in this way the mechanical yields on shaft. The encased joint stator winding is not movable and it can be both single and three phased. The inductive field (rotor) is made up of permanent magnets and the induced (stator) is equipped with single phased winding situated on the surface of cylindrical yoke laminations. The subsystems rotor and stator are independently sealed; water can flow into the space between the fittings and in the camps.
