Method and apparatus for thermal examination of the interior surface of annular stator packs for electrical machines

A method for investigating the quality of active-steel stator packs for an electric machine in which an infrared heat sensor is introduced into the bore of a stator to carry out continuous measurement of the entire inner surface of the stator, the result being obtained in the form of an infrared cha...

Zusammenfassung:A method for investigating the quality of active-steel stator packs for an electric machine in which an infrared heat sensor is introduced into the bore of a stator to carry out continuous measurement of the entire inner surface of the stator, the result being obtained in the form of an infrared chart made to scale, the contrast areas of the chart serving to determine the coordinates and shape of the excess-heating zones in the active steel of the stator.
