Summary:A bandage for a rotor of an electrical machine that may be used in an electrical drive system of an aircraft is provided. The bandage, which serves to fix permanent magnets to the rotor, includes two rings, which are coaxial circular ring-like components, that are connected together by axial webs. The permanent magnets each have axial grooves on a surface of the respective permanent magnet facing the stator. The bandage is arranged on the rotor such that the permanent magnets lie between the rings, and the axial webs are positioned in the axial grooves. Since a thickness of the axial webs corresponds to a depth of the axial grooves, the magnet surfaces and the surface of the bandage are flush with one another, such that the bandage requires no additional space in an air gap.
