Vibration wave driven motor. |
摘要 |
<p>A vibration wave driven motor produces a travelling wave in an elastic body and thereby moves the elastic body relative to a member pressed against the elastic body. The travelling wave is a combination of a plurality of standing waves generated by application of out-of-phase alternate electric fields to a plurality of driving element groups for an electro-mechanical energy conversion element bonded to the elastic body. The electro-mechanical energy conversion element has an electrode which is patterned such that cuts thereof coincide with the nodes of the standing wave generated in the elastic body.</p> |
