Patent

CA 2497177

The invention relates to a rotary piezoelectric motor (1) in which a geometrical asymmetry can be introduced, e.g. in the counter-masses (11, 14) or in the stator fixing means (10), in order to produce a phase shift previously obtained using a phase quadrature power supply. A simplified single-phase power supply (40) can be used with one such motor. The inventive motors offer advantages in terms of cost and reliability, particularly for motors that require only a single direction of rotation. Said motors are particularly suitable for small motors such as those used for clock and watch making, microsurgery or microelectronics.

Moteur rotatif piézo-électrique (1) où l'introduction d'une dissymétrie géométrique, par exemple dans les contre-masses (11, 14) ou dans la fixation du stator (10), permet d'obtenir un déphasage autrefois obtenu à l'aide d'une alimentation électrique en quadrature de phase. Un tel moteur permet d'utiliser une alimentation simplifiée monophasée (40). De tels moteurs présentent des avantages économiques et de fiabilité, essentiellement pour des moteurs qui ne nécessitent qu'un seul sens de rotation. Ils sont particulièrement adaptés pour les moteurs de petite taille tels les moteurs d'horlogerie, de microchirurgie ou de microélectronique.
