The end portions (9, 10) of the support elements are in engagement with the recesses (8) to fix the end rings and support elements to each other. Furthermore, the inner sides (14) of the support elements (3) coincide with the support surfaces (7) of the end rings and the end surfaces (11, 12) with the outer sides (5) of the end rings. A method is also described for manufacturing said coil, commencing with assembling said core.</p> |
