A device, particularly for driving recording or printing carriages in data recorders and the like, utilizing a linear motor, in which a current carrying coil is movably guided along a pair of ferromagnetic rails which are magnetically polarized by suitable magnetizing means to produce a directional field between the rails, whereby the current carrying coil is moved along the rails in response to current passing through the coil. Means are also provided for controlling the movement of the coil in predetermined stabilized steps.
