Abstract
A coil for an electric motor, which is to be inserted into a pole shoe and is wound, before the insertion, in a template, includes two cases of insulating material, which are positioned in mirror-inverted relationship with one another. Pockets are provided laterally of the cases to receive contact terminals therein. The pockets form limiting surfaces for limiting the insertion of the coil into a pole shoe. Each case is closed, after the coil winding has been completed, by connecting two upper portions thereof to each other by welding or glueing.
