Abstract

An electric motor, comprising at least a stator, which extends between a first end face and a second end face along an axial direction and has an annular yoke on the first end face and starting from the yoke a plurality of cores, which each extend along the axial direction over a first length to the second end face and are arranged adjacent to one another along a circumferential direction, wherein a coil is arranged on each core, which coil extends starting from the yoke along the axial direction over a second length toward the second end face. The second length is shorter than the first length, so that a portion of each core extends along the axial direction beyond the coil concerned. The motor additionally comprises at least one first rotor which is arranged, at least on the second end face along the axial direction between the coils and the second end face.
