Title: ELECTRIC MOTOR
Abstract:
The present invention relates to an electric motor (1), in particular for a motor vehicle (2), comprising an internal rotor (3) which is mounted such that it can rotate about a rotation axis (5) relative to an external stator (4), wherein the rotor (3) has a pot-like rotor receiving sleeve (7), which is arranged around a rotor shaft (6), for receiving an armature unit (8) which has a multilayered laminated core (9) with a plurality of permanent magnets (10), wherein the rotor receiving sleeve (7) is closed in a fluid-tight manner by a cover (11). It is essential to the invention here that the permanent magnets (10) are arranged on a radial outer side (13) of the laminated core (9) at a distance from one another in the circumferential direction (12), and that first retaining apparatuses (14) are integrally formed on the laminated core (9) in intermediate spaces (43) of adjacent permanent magnets (10) and prevent slipping in the circumferential direction (12).
