Beschreibung
Zusammenfassung:	A permanent magnet electrical machine (10) includes a rotor body (130) and a plurality of permanent magnet modules (101) arranged around a rotational axis (Y) of the permanent magnet electrical machine (10), each permanent magnet module (101) comprising at least a permanent magnet (200) and a baseplate (301), the baseplate (301) including a base side (311) for attaching the permanent magnet module (101) to the rotor body (130) of the permanent magnet machine (10) and an opposite top side (312) for attaching the permanent magnet (200) to the baseplate (301). The rotor body (130) includes at least a cavity (210) housing a non-magnetic and/or non-conductive medium for creating a magnetic flux barrier between the rotor body (130) and the permanent magnet module (101). The baseplate may include a protrusion. The protrusion may be shaped as a dovetail. One or elastomeric inserts (350) may be provided between the baseplate (301) and the rotor body (130) .
