34-10 GENERATOARE CU MAGNEȚI PERMANENȚI PENTRU AGREGATE EOLIENE ȘI HIDRAULICE
PERMANENT MAGNETS GENERATORS FOR
WIND AND WATER PLANTS
This paper presents some particularities in the construction of synchronous generators for wind and hydro-plants and low power generators with permanent magnets with a simplified construction. Also, a comparison between variants of generators with electromagnetic excitation and permanent magnets is done.
The advantages of the use of supermagnete from rare earths, Neodim Iron Bor (NeFeB), especially the increase of the efficiency of these generators, are highlighted, and finally the maximization of efficiency is mentioned by replacing the conductive materials (copper, aluminium) with superconducting ceramic materials at ambient temperature.
