Title (EN) MAGNETIC SPRING SYSTEM FOR USE IN A RESONANT MOTOR
(FR) SYSTÈME À RESSORT MAGNÉTIQUE À DES FINS D'UTILISATION DANS UN MOTEUR À RÉSONANCE
Abstract:
(EN) A magnetic spring arrangement for a resonant motor, comprising: a housing (12), magnets (14, 16) fixed in position at opposing ends (13, 15) of the housing, a magnet (18) positioned within the housing for movement toward and away from the fixed magnets in a reciprocal oscillating motion with a driving action produced by a stator coil (24) and an AC drive signal (26), wherein an applicator member (32) is attachable to the moving magnet for corresponding movement of a workpiece portion (34) of the applicator member.
(FR) L'invention concerne un système à ressort magnétique pour un moteur à résonance, comportant : un logement (12), des aimants (14, 16) fixés en place aux extrémités opposées (13, 15) du logement, un aimant (18) positionné à l'intérieur du logement à des fins de mouvement vers et en provenance des aimants fixes selon un mouvement d'oscillation réciproque avec une action d'entraînement produite par une bobine de stator (24) et un signal d'entraînement c.a. (26), un organe applicateur (32) pouvant être attaché à l'aimant mobile à des fins de mouvement correspondant d'une partie pièce (34) de l'organe applicateur.
