The drive system for a personal care appliance, such as a toothbrush, includes a first opposing pair of permanent magnet assemblies positioned longitudinally along the length of the internal surface of a cylindrical appliance housing(12) , each first permanent magnet assembly having one portion with a north polarity and the other portion a south polarity, and a second pair of permanent magnet assemblies which are orthogonal to the first pair of permanent magnet assemblies, one second permanent magnet assembly having a plurality of abutting first parts along the length thereof, the parts alternating between a north polarity and a south polarity, the other second permanent magnet assembly having similar parts with reversed polarity. First and second armatures (30, 32) are mounted on, or a portion thereof forms, a spindle element (34) which extends along the length of and outward from the cylindrical housing. A plurality of drive windings (36,38,40,42) are positioned around the armatures in such a manner that application of current to the windings, under programmable control, produces axial and/or tangential movement of the spindle and the workpiece .

Le système d'entraînement d'un article d'hygiène tel qu'une brosse à dents comporte une première paire d'aimants permanents opposés placés longitudinalement le long de la surface intérieure du logement d'un dispositif cylindrique, chacun des aimants de la première paire d'aimants présentant une partie de polarité nord et une partie de polarité sud. Le système comporte également une deuxième paire d'aimants permanents, orthogonale à la première, dont l'un présente plusieurs premières parties formant des butées, disposées le long dudit aimant et de polarités NS alternantes, et dont l'autre présente des parties semblables mais de polarité inverse. La première et la deuxième armature sont montées sur, ou une de leur partie, forme un élément de broche s'étendant le long et vers l'extérieur du logement cylindrique. Plusieurs enroulements d'excitation sont disposés autour des armatures de manière à ce que, la mise sous tension par une commande programmée produise un mouvement axial ou tangentiel de la broche et la pièce à usiner.
