CA 2138350

A flat commutator includes sectorial carbon segments 1 made of conductive carbon elements to provide a commutating surface of the commutator, a metallic segment 4 on which the carbon segments 1 are arranged circularly and a hub body 7 of synthetic resin. The metallic segment 4 has fixing members 5 to encroaching onto inner and outer peripheral surfaces of the carbon segments 1, thereby fixing the segments 1 on the metallic segment 4. The hub body 7 encloses at least fixed portions of said inner and outer peripheral surfaces of the carbon segments 1. In arrangement, the fixed portions engage with the fixing members 5 of the metallic segment 4, respectively.

Commutateur plat comprenant : des segments de carbone sectoriels (1), constitués d'éléments de carbone conducteurs, fournissant une surface de commutation pour le commutateur; un segment métallique (4) sur lequel les segments de carbone (1) sont disposés en cercle; un corps de moyeu (7) de résine synthétique. Le segment métallique (4) possède des éléments de fixation (5) permettant un empiètement sur les surfaces périphériques intérieure et extérieure des segments de carbone (1), ce qui permet de fixer ces segments (1) sur le segment métallique (4). Le corps de moyeu (7) entoure au moins des parties fixes des surfaces périphériques intérieure et extérieure des segments de carbone (1). Selon ce système, les parties fixes s'engagent respectivement avec les éléments de fixation (5) du segment métallique (4).
