Electric motor with split magnetic return element
Abstract:
The invention relates to an electric motor (10) and to a method for producing said electric motor, especially for adjusting mobile parts in a motor vehicle. Said electric motor comprises a rotor (12), a lower housing part (16) and an upper housing part (18) which can be radially assembled in relation to the rotor (12), and at least two permanent magnets (22) that are coupled to each other by means of a magnetic feedback element (24). Said feedback element comprises a lower feedback sheet (28) and an upper feedback sheet (30), the upper feedback sheet (30) having a stop face (40) that rests on a mating stop face (42) of the lower housing part (16).
