Abstract
The stator is formed by a pack () of stacked magnetic laminations (), each of which has a central opening () and a plurality of peripheral holes (), in such a way that the overlapping of identically shaped holes () in the laminations () defines respective passages through the pack (). The faces of the laminations () are substantially flat and retaining means are associated with the holes () in an end lamination () of the pack (), these means protruding into the openings of the respective holes () in the end lamination () without interfering with the other laminations () of the pack (). The corresponding production process provides for: inserting a pin () into each of the passages through the pack () at the end of which the retaining means are located, these means retaining the pin () and keeping the pack () close-packed; subjecting the close-packed pack () to heat treatment; releasing the pins () from the grip of the retaining means; and extracting them from the corresponding passages.
