Single-phase electroactive motor |
摘要 |
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 elements ( 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. The motors are particularly suitable for small motors such as those used for clock and watch making, microsurgery or microelectronics.
