Abstract
A method for determining the position at rest of a rotor of a machine having at least one excitation winding. The invention provides a technique for detecting the position of the rotor at rest, from information contained in the voltages produced at the terminals of the stator windings, when the voltage applied to the rotor winding undergoes variations. The invention thus makes it possible to detect the rest position of the wound-rotor machine in the absence of ordinary position sensors such as magnetic, optical, resolving, mechanical, capacitive or other sensors.
