Piezoelectric linear step motor and variants

摘要

A piezoelectric linear stepping motor comprises a housing (1), a movable part (4); between them there are provided fixing units made in the form of two piezoelectric units: a shifting-and-fixing unit (2) and a fixing unit (3) which consist of piezoelectric cells (7,8,9), insulators (5) and friction elements (6), the movable part (4) being in contact with the friction elements (6).
