The present invention relates to a method, an apparatus and a computer program for inspecting laminated iron cores (1) of electrical machines for interlamination shorts, in which the laminated iron core (1) is magnetized by means of an auxiliary winding, and the iron surface is scanned by means of at least one measurement coil arrangement (2) with a downstream measurement device. In this case, unique and quantifiable localization of interlamination shorts is achieved by using both the phase (8) and the amplitude (7) of the electrical signal which is induced in the at least one measurement coil arrangement (2), in combined form.
Procédé et dispositif ainsi que programme informatique de contrôle d'empilements de tôles de fer feuilletées (1) de machines électriques à la recherche de courts-circuits entre tôles. Selon ledit procédé, l'empilement de tôles de fer feuilletées (1) est magnétisé à l'aide d'un bobinage auxiliaire et la surface du fer est palpée à l'aide d'au moins un ensemble bobine de mesure (2) doté d'un appareil de mesure monté en aval. Il est ainsi possible de localiser de manière univoque et quantifiable des courts-circuits entre tôles du fait que tant la phase (8) que l'amplitude (7) du signal électrique induit dans l'ensemble bobine de mesure (2) au moins sont utilisées de manière combinée.
