Abstract
(EN) Disclosed is a DC motor equipped with: a stator having a plurality of field poles; an armature equipped with an armature core, an armature coil, and a commutator; and a brush that is in sliding contact with the commutator. The armature coil comprises coil units with concentrated windings that are wound around various teeth, and crossover units that connect therebetween and are electrically connected. Commutator segment groups comprise adjacent first and second segments to which the coil units with concentrated windings connect and third segments to which only the adjacent crossover units connect. In addition, the plurality of crossover units include crossover units that connect between the coil units with concentrated windings by passing through a slot.
(FR) La présente invention concerne un moteur à courant continu qui est muni : d'un stator comportant une pluralité de pièces polaires ; d'une armature dotée d'un noyau d'induit, d'une bobine d'armature et d'un collecteur ; et d'un balai qui est en contact coulissant avec ledit collecteur. La bobine d'armature comprend des unités de bobine dotées d'enroulements concentrés qui sont enroulés autour de différentes dents, et des unités de jonction qui sont connectées entre les unités de bobine et sont connectées électriquement. Des groupes de segments de collecteur se composent de premiers et deuxièmes segments adjacents auxquels sont connectées les unités de bobine dotées d'enroulements concentrés, et de troisièmes segments auxquels sont connectées uniquement les unités de jonction adjacentes. En outre, la pluralité d'unités de jonction comportent des unités de jonction qui sont connectées entre les unités de bobine dotées d'enroulements concentrés en passant à travers une fente.
