Abstract

A linear unit comprises carriage which is arranged longitudinally displaceably in a holder and is driven by a linear motor, the rotor of which is designed as a flexible strip with a tooth structure consisting of magnetic metal. The strip is fixed self-supportingly on the carriage at its two ends and is guided on both sides on the surfaces of the stators of the linear motor bounding the pole gap.
