Beschreibung
Zusammenfassung:	It is described a method of measuring a size (d) of an air gap(ag) between a rotor surface (107) and a stator surface (110) of an electrical machine (100), in particular permanent magnet machine, the method comprising: performing a measurement based on electromagnetic radiation, in particular using at least one measurement probe installed at the stator and/or the rotor, to obtain air gap size related information to obtain air gap size related information; determining the size (d) of the air gap (ag) based on the air gap size related information.
