Abstract
The moving part, designed to move past a fixed rotor with coils, comprises a metallic chassis to which magnets, arranged in parallel rows of alternating polarity, are bonded. Non-metallic fixing strips, screwed to the chassis, are positioned longitudinally between each row of magnets, extend along the entire length of these rows and mechanically immobilize the magnets. Each fixing strip comprises a bearing base with convex rounded flanks which immobilize the magnets vertically and collaborates with a concave rounded portion, formed in the adjacent edge face of the magnets over at least half of the height thereof. The strip also comprises a longitudinal upper extension acting as a spacer between the rows of magnets and immobilizing the magnets laterally. The invention is of benefit to the manufacturers of rotary or linear electrotechnical machines such as motors or generators.
