Abstract

A linear drive having a device for sensing and evaluating an operational force acting on the linear drive is to be of simple design and is to be constructed so as to be functionally effective with a high degree of accuracy. For this purpose, the operational force on the bearing part supporting the displaceable part of the linear drive in a housing is sensed and electronically evaluated by a magnetostrictive force sensor.
