Title (EN) A ROTATOR FOR A COMMUTATOR MOTOR AND AN ELECTRIC TOOL HAVING THE SAME
(FR) ROTATEUR DE MOTEUR À COLLECTEUR ET OUTIL ÉLECTRIQUE L’UTILISANT
Abstract:
(EN) There is provided a rotator for a commutator motor which comprises a rotating shaft 14, a rotator core 25 which is firmly fixed on the rotating shaft 14, a commutator 28 which has commutator pieces having integral multiplication of a number of slots of the rotator core 25, a rotator coil 27 which is coiled around the rotator core 25 and whose the end portion is connected to the commutator piece, and a shaft insulators 29a and 29b which electrically insulates the rotator coil 27 and the rotating shaft 14, a part of the coil end portion 27 exposed from the rotator core 25 of the rotator coil 27 being covered with an elasticized protection sheet 30 having a mesh and the protection sheet 30 being firmly fixed on the coil end portion 27a by impregnation and hardening of resin, in which the protection sheet is provided with a parallel portion abutting to the rotating shaft or shaft insulator approximately in parallel.
(FR) La présente invention concerne un rotateur de moteur à collecteur comprenant un arbre rotatif (14), un mandrin de rotateur (25) qui est fermement fixé sur l’arbre rotatif (14), un collecteur (28) qui comporte des pièces de collecteur toutes dotées d’un même nombre de rainures du mandrin (25), une bobine de rotateur (27) qui est enroulée autour du mandrin (25) et dont la partie terminale est reliée à la pièce de commutateur, et des isolateurs d’arbre (29a et 29b) qui isolent électriquement la bobine (27) et l’arbre rotatif (14). Une section de la partie terminale de la bobine (27) est exposée à partir du mandrin (25) de la bobine (27), celle-ci étant recouverte d’une feuille de protection élasticisée (30) à maille, ladite feuille (30) étant fermement fixée sur la partie terminale de la bobine (27a) par imprégnation et durcissement de résine, la feuille de protection comprenant une portion parallèle aboutée à l’arbre rotatif ou à l’isolateur d’arbre à peu près en parallèle.
