摘要：
A new type linear USM with double- driving feet has been developed. The stator consists of eight piezoelectric ceramic plates and one plate. Piezoelectric ceramics plates are polarized along the thickness and are symmetrically bonded to the two surfaces of one rectangle brass plate. Double- driving feet are assembled on the same side of the brass plate. The working vibration mode is a composite inplane bimode, which consists of the first longitudinal in- plane vibration mode and the second bending one. The basic size of the linear is determined carefully by FEA. The characteristics of the prototype motor were measured experimentally. (c) 2006 Elsevier B. V. All rights reserved.
