Abstract
(EN)
A rotary electric machine (10) is provided with: a magnetic field element (40) that has a magnet part (42) including a plurality of magnetic poles having polarities alternately arranged in the circumferential direction; and an armature (50) that has a multi—phase armature winding wire (51). The magnetic field element or the armature serves as a rotor. A protection band (1000, 1020, 2000, 3000) which is a magnetic body is provided between the magnet part and the armature winding wire in the radial direction.

L'invention concerne une machine électrique tournante (10) qui est équipée: d'un élément de champ magnétique (40) comportant une partie d'aimant (42) comprenant une pluralité de pôles magnétiques, ayant des polarités alternées dans la direction circonférentielle, et d'une armature (50), possédant un fil de bobinage d'armature à multiples phases (51). L'élément de champ magnétique ou l'armature sert de rotor. Une bande de protection (1000, 1020, 2000, 3000) qui est un corps magnétique est disposée entre la partie d'aimant et le fil de bobinage d'armature dans la direction radiale.
