Abstract

An internal rotor motor, in particular an electronically commutated internal rotor motor, comprising: a multipole stator (28); a rotor lamination stack (37; 52, 54, 56) rotatably mounted relative to this stator; a central recess (47) provided in the rotor lamination stack, wherein the rotor lamination stack comprises individual laminations (41) whose central recesses (47) have radially inner first sections (50) into which a shaft (18) is pressed, and these central recesses (47) have second sections (51) in the areas between the radially inner first sections (50), which are spaced apart from the outside of the shaft (18) in the assembled state, wherein the individual laminations (41) are arranged angularly offset from one another in a central area of ​​the rotor lamination stack (52), wherein at least one end (52A, 52B) of the rotor lamination stack (37; 52, 54, 56) has a predetermined number of The individual sheets (41) are not arranged at an angle to each other.
