Summary:An electric motor (100) has: an external stator (28); an internal rotor (150), which is arranged rotatably moveably in the external stator (28) and has a laminate stack (200; 200'; 200"), which has a plurality of rotor laminations (210, 202; 201', 201") and in which at least one first cutout (614) and at least one second cutout (630) are provided, wherein the first cutout (614) is assigned a rotor magnet (224) arranged therein, wherein the second cutout (630) is assigned a jamming element (40) arranged therein, wherein a clamping member (692, 694) is provided between the first cutout (614) and the second cutout (630), and wherein the jamming element (40) and the second cutout (630) are designed to make it possible for the jamming element (40) to be supported on the laminate stack (200; 200', 200"), and to apply a force (F) to the clamping member (692, 694) in the direction towards the rotor magnet (224), wherein the second cutout (630) is formed by the through-opening (630) for accommodating a shaft (40), and wherein the jamming element (40) is formed by the shaft (40).
