Electric motor
First Claim
1. A multiphase electric motor comprising a stationary part and movable active motor parts, the active motor parts including a motor winding for each phase and a motor magnet, an air gap being formed between said active motor parts, each motor winding built on a synthetic resin foil and formed through local removal of copper material with which the synthetic resin foil had previously been fully coated to form planar coils having individual conductor tracks mutually spaced from each other by gaps created by the local removal of the copper material with adhesive filler material filling all gaps so as to interconnect and thereby improve the stability of the tracks.

Abstract
In an electric motor with a stationary and a movable active motor part, one of the two active motor parts comprising a motor winding and the other a motor magnet, an air gap being formed between said active motor parts. The motor winding (9) is built up on a synthetic resin carrier foil and is formed through local removal of copper material with which the synthetic resin foil (23) had previously been fully coated. The synthetic resin carrier foil (23) and the planar coils (28) adhering thereto are provided with an adhesive filler material (30) such that the adhesive filler material (30) fills up the gaps (26) formed between the individual conductor tracks through the removal of the copper material. The assembly thus stabilized is wound into an evenly rounded cylinder.
