Beschreibung
Zusammenfassung:	The present invention relates a device for magnetizing a rotor of an electrical machine with a power rating of at least 1 MW, wherein the rotor comprises permanent magnet material, said device comprising a yoke with an electromagnetic coil arranged to produce a pulsed magnetic field for magnetizing the permanent magnet material, wherein the magnetic field is sufficient to magnetize a permanent magnetic pole wherein the rotor and yoke is in a fixed relation to each other. The invention also relates to a method for magnetization of a rotor with permanent magnets for an electrical machine.
