Abstract

Procedeu, conform revendicarii 1, caracterizat prin aceea ca, în scopul racirii bune a bobinelor statorice (4), consta în înglobarea în masa termoplastica (2) numai a tolelor statorice (3), segmentele statorice (1) identice avînd, în acest caz, în dreptul portiunii de jug (c) a statorului (A), cîte un locas interior (g) delimitat de suprafetele polilor (b) si cîte un locas exterior (h), format între doua nervuri (i), obtinute prin turnarea masei termoplastice (2), în aceste locasuri înfasurîndu-se bobinele statorice (4), dupa turnarea masei termoplastice (2).
