Abstract
The invention relates to a direct linear drive having a stator (12; 112) and a runner (14; 114), to at least one of which electric energy can be applied in order to initiate a translational movement on a coupling element (36; 136); and having a position sensing device (16; 116) for determining the position of the runner (14; 114) in relation to the stator (12; 112); it further relates to a drive device with a direct linear drive of this type and to an actuating device which is equipped with a drive device of this type. According to the invention, the position sensing device (16; 116) is designed as a linear position sensor with a magnetostrictive measuring element (54; 154) and an associated measurement transducer (58; 158).
