Abstract
(EN)
A motor includes an annular armature 2 having nine teeth 211. One conducting wire is successively wound on the three teeth 211, thereby forming a coil group. Three coil groups are connected by delta connection. On upper surfaces of the insulators 22a and 22b, two grooves 221 for holding bus bars 24a to 24c are formed. The number of bus bars held by one insulator is two at the maximum in the radial direction. Accordingly, the space required for placing the bus bars on the armature can be reduced, and the radial and axial sizes of a motor 1 can be reduced.

La présente invention concerne un moteur qui comprend une armature annulaire (2) qui possède neuf dents (211). Un fil conducteur est enroulé successivement sur les trois dents (211), formant ainsi un groupe de bobine. Trois groupes de bobines sont connectés par connexion delta. Sur des surfaces supérieures des isolants (22a et 22b), deux rainures (221) destinées à retenir des barres omnibus (24a à 24c) sont formées. Le nombre de barres omnibus retenues par un isolant est deux au maximum dans la direction radiale. En conséquence, l'espace requis pour placer les barres omnibus sur l'armature peut être réduit, et les tailles radiale et axiale d'un moteur (1) peuvent être réduites.
