| 摘要 |
<p>The invention relates to a piezoelectric motor. This motor includes: - a support (2), - a stator (S2, S3) integral with the support (2), - piezoelectric means (10) capable of being electrically excited in order to impart a vibratory movement to the stator (S2, S3), - a rotor (R2, R3) mounted so as to rotate with respect to the support (2), this rotor including a body on which transmission means (36) are arranged, which are configured to transmit the vibratory movement from the stator (S2, S3) to the rotor (R2, R3) and to drive this rotor in rotation, and - means (79) for elastically supporting the rotor on the stator, characterised in that the body of the rotor is formed by a structure (D2, D3) which is elastically deformable, at least towards the stator, and which, at least in part, forms the support means (79). The invention applies, for example, to a timepiece. <IMAGE></p> |
