Beschreibung
Zusammenfassung:	The invention relates to an electric machine comprising a permanent magnet arrangement and an electromagnetic arrangement. The electromagnetic arrangement comprises a first number of excitation coils, each excitation coils being wound around a pole core. The permanent magnet arrangement comprises a second number of magnet segments formed of a permanently magnetic material. An air gap is arranged between the electromagnet arrangement and the permanent magnet arrangement. The magnet segments have a permanent magnetisation in a first magnet segment volume. At least one magnet segment comprises a demagnetised region in a second magnet segment volume.
