In line DC motor with a permanent magnet arrangement displaying a ferromagnetic ground and a multi-strand winding, which are linearly moveable with respect to one another, in particular for drives in data engineering. The winding consists of several coils following one another in the direction of movement, activatable with current in cyclic sequence, which in each case are layed without overlap around a pole of at least one grooved flow guidance part which together with the permanent magnet arrangement forms an essentially even air gap, with coil axis standing perpendicular to the direction of movement. The ratio of coil interval to magnet interval amounts to 2:3. To make interfering reluctance forces ineffective, in the vicinity of the sides of the end poles lying in the direction of movement, ferromagnetic auxilliary poles are provided.
