Abstract
The invention concerns both a method for controlling a traversing device driven by a stepping motor and a traversing device, in which the position of a traversing thread guide which is moved to and fro within a traversing stroke is determined by the position of a rotor of the stepping motor, the rotor moving within a stator of the stepping motor with several windings. The movement of the rotor is controlled, according to the invention, by a stator flux which is determined by a stator voltage generated by means of a flux control device.
