摘要： A method for determining the polarity of a pole of a rotor of an electrical rotating machine, having an estimated position in relation to a stator, said method including the following steps: a) applying an excitation voltage to the stator such as to generate two different magnetic fluxes successively inside a saturable magnetic zone of the pole, one flux in conjunction with and the other in opposition to the magnetic flux of the magnets, such as to saturate the saturable magnetic zone for at least one of the magnetic fluxes; and b) determining the polarity of the pole according to the differences in the temporal evolution of the current generated in the stator by the two fluxes.

摘要： The invention relates to electromechanical assemblies comprising an alternator, especially of high power, typically greater than or equal to IMW, and a converter, the alternator comprising a rotor driven in rotation, by a wind turbine for example, and more particularly to wound rotor synchronous alternators. The drive can also take place by means of a tide-driven, hydraulic or marine-current-driven generator. An alternator comprises in a manner known per se a field winding, generally at the rotor, supplied with DC current either by split rings and brushes, or by an exciter, so as to generate in an armature winding, generally at the stator, an AC voltage.
