Patent

CA 2200775

The invention relates to an electromagnetic claw-pole rotor consisting of parts made of magnetic material (1, 9) forming the poles (3, 30) of the rotor and parts made of non-magnetic material (12) separating opposing poles (3, 30), housed in a hollow revolving carter cylinder (13) made of non-magnetic material; it has two single-pole end parts (1) made of magnetic material with opposite polarities, at least one mid piece (9) made of magnetic material, and parts made of non-magnetic material (12), each part (1), a bevelled pole (3) and two flat lateral surfaces (6) being symmetrical with the plane of symmetry of the bevelled pole (3), the mid piece(s) (9), consisting of the two poles (30) with opposite polarities, having the same shape as the poles (3) of the end parts (1), each pole (3, 30) being separated from the pole (30, 3) opposite by a non-magnetic part (12) that is complementary in shape to the two poles (3, 30), the carter cylinder (13) having as many transversal openings (15) as there are poles (3, 30) and each opening (15) being fitted with a distal tube component (14, 140) made of magnetic material of the same polarity as the pole (3, 30) to which it is associated.

L'invention concerne un rotor magnétoélectrique à griffes du type comprenant des pièces en matériau magnétique (1, 9), formant les pôles (3, 30) du rotor, et des pièces en matériau amagnétique (12), de séparation des pôles (3, 30) de polarité opposée, confinés dans un cylindre carter creux de révolution (13) en matériau amagnétique, selon l'invention il comprend deux pièces d'extrémité (1) mono pôle en matériau magnétique de polarités opposées, au moins une pièce intermédiaire (9) en matériau magnétique et des pièces en matériau amagnétique (12), chaque pièce (1) mono pôles, un pôle (3) en biseau, et deux faces latérales planes (6) symétriques par rapport au plan de symétrie du pôle (3) en biseau, la ou les pièce(s) intermédiaire(s) (9) comprenant deux pôles (30) de polarités opposées, ayant la même forme que les pôles (3) des pièces d'extrémité (1), chaque pôle (3, 30) étant séparé du pôle (30, 3) en regard par une pièce amagnétique (12) de forme complémentaire des deux pôles (3, 30), le cylindre carter (13) ayant autant de fenêtres traversantes (15) qu'il y a de pôles (3, 30) chaque fenêtre (15) étant occupée par un élément de tube distal (14, 140) en matériau magnétique de même polarité que le pôle (3, 30) auquel il est associé.
