The invention relates to an electric motor, comprising a stator, on which at least one coil for generating a commutated magnetic rotating field is designed, and a rotor, on which at least one permanent magnet element is designed, wherein the rotor is mounted rotatably on an axis, and wherein a force acts between the commutated magnetic rotating field and the magnetic field of the permanent magnet element, said force rotating the rotor about the axis thereof. In order to provide an electric motor in which the at least one permanent magnet element is fastened on the rotor in a cost-effective and long-term stable manner, wherein the torque generated by the electric motor should be as large as possible, the at least one permanent magnet element protrudes in an axial extension thereof beyond the stator, wherein exclusively the part of the permanent magnetic element that protrudes beyond the stator is covered by an overmolding made of a plastic material, wherein said overmolding fixes the permanent magnet element in the position thereof on the rotor. |
