Abstract
A preformed coil () to produce a self-supporting air-gap skewed winding of a small electric motor consisting of at least two preformed coils () positioned overlapping on a circumference of a winding () and a method and device for producing the coil. Two preformed coil sides () lying in different radial planes are formed which are connected on their front ends () by front connections. The front connections feature the radial plane offset from the winding offset sections () bridging the preformed coil sides (). The preformed coil sides () are formed curved with a circular shape around a longitudinal axis (), and the radius of curvature of the one radial outer preformed coil side () is greater than the radius of curvature of the radial inner preformed coil side ().
