Rezumat: Problematica generatoarelor sincrone excitate cu magneti permanenti, utilizate in conversia energiei –ca particularitati disticte de proiectare optimala - este una de actualitate. In lucrare se dezvolta o metoda noua de determinare a numarului de crestaturi pe pol si faza pe baza estimarii temperaturii la nivelul izolatiei crestaturii statorice, avand la baza algoritmul Poynting [14]. In functie de obiectivul urmarit, optimizarea numarului de crestaturi conduce la optimizarea concomitenta a consumului de materiale, sau a costului

Cuvinte cheie: crestaturi pe pol si faza, generatoar sincron cu magneti permanenti, optimizare termica


Abstract: The issue of permanent magnet synchronous generators, used in wind energy conversion system, as distinct features of optimal design - is a current one. The paper develops a new method for determining the number of slots per phase and pole based on the estimation of stator slot insulation temperature, using Poynting vector algorithm [14]. Depending on the objective pursued, optimization of the number of slots per phase and pole leads to simultaneous optimization of active material consumption, or cost.

Keywords: slot per phase and pole, permanent magnet synchronous generator, thermal optimization
