Abstract

A rotor of an electric machine includes a plurality of permanent magnets arranged on an exterior of the rotor, and a bandage tape wound around the permanent magnets for fixing the permanent magnets in place. The bandage tape includes a first tape end, which is fastened to a surface of at least one permanent magnet, and a second tape end, which is an end of an outermost tape section of the bandage tape and is fastened to a tape section of the bandage tape disposed below the outermost tape section. The bandage tape is wound around the permanent magnets with a prestress such that in a region of each permanent magnet, at least one tape section of the bandage tape has a predeterminable minimum prestress.
