摘要： An electric motor having a stator and a rotor rotatably mounted about a rotational axis relative to the stator is disclosed. The rotor additionally has a main part, multiple magnet elements which are distributed along the circumferential direction and are received on a radial face of the main part in a mutually spaced manner, and a burst-protection sleeve which covers the main part and the magnet elements. The burst-protection sleeve has multiple cover segments, each of which directly contacts a magnet element, and multiple bridging regions which connect two adjacent cover segments together, wherein the burst-protection sleeve is used to directly support the magnet elements relative to the main part, and the bridging regions have a lower degree of flexural strength in the circumferential direction than the cover segments.
