A flat coreless vibrator motor includes a casing for housing the motor, a shaft rotatably supported by the casing, a rotor mounted on the shaft and being generally in the shape of a sector, the shaft being disposed at the center of a circle along which a generally arc-shaped outer periphery of the sector generally extends. At least three armature coils are provided on the rotor and are angularly arranged in such a manner that these armature coils do not overlap each other. A magnet is mounted on the casing so as to generate a magnetic flux. A commutator and brushes cooperate with each other so as to supply electric power to the armature coils. Since the rotor is eccentric, vibration are produced during the rotation of the rotor.
n moteur à vibreur plat sans noyau comprend un carter qui enveloppe le moteur, un arbre avec appui lui permettant de tourner dans le carter, un rotor monté sur l'arbre et présentant la forme générale d'un secteur, l'arbre étant placé au centre d'un cercle en bordure duquel se trouve le périmètre extérieur en forme générale d'arc du secteur. Au moins trois bobines d'induit équipent le rotor et sont angulairement disposées de façon à ne pas se chevaucher. Un aimant est monté sur le carter dans le but de générer un flux magnétique. Un collecteur et des balais se complètent en vue d'alimenter en courant électrique les bobines d'induit. Le rotor étant excentrique, sa rotation produit des vibrations.
