An electric motor () features a external stator (), an internal rotor () rotatably mounted within the external stator, the rotor having a lamination stack (&#x2033;) composed of a plurality of rotor plates (&#x2033;) in which are formed at least one first recess () and at least one second recess (), a rotor magnet () being located in each first recess (), the second recess () being associated with a jamming element () mounted therein. A clamping member () is arranged between the first recess () and the second recess (). The clamping member and the second recess () are shaped so as to enable support of the jamming element () on the lamination stack, and to permit application of a force (F) on the clamping member in the direction of the rotor magnet. The second recess () serves as a through-opening for receiving a shaft (), and the shaft () serves as the jamming element ().
