Abstract

The piezoelectric linear motor is intended for driving printing heads. It comprises two walls whose serrated sides face each other. The moving part is suspended from a carrier which runs on the angled tops (2, 2') of the walls. The moving part consists of a piezoelectric column arranged in bellows form and held by axial springs between end plates. On each side are a pair of springs with hooked ends which engage with the wall serrations. These springs are also driven by a piezoelectric effect. To move one step one set of springs is energised and locks onto the walls. The column is then energised and expands after which the second set of springs is energised. The first spring set is then released, and when the column is subsequently switched off it contracts.
