1. A method of producing an add-on part of a drive, said method comprising:
providing one circuit board of multiple planar circuit boards, which have electrical conductor tracks with electrical connections, with a centrally arranged opening for passage of a shaft;
populating the circuit boards with electrical and/or electronic components;
electrically testing the populated electrical and/or electronic components and wiring;
arranging segments made of a material with high thermal conductivity on at least two of the multiple circuit boards such that a bending process in a region of the electrical connections between the at least two circuit boards causes the segments to form an approximately peripherally closed cover; and
arranging lids on open sides of the cover to realize a closed housing arrangement.
