Abstract
A slotless rotating electric machine includes a rotor having multiple alternating polarity permanent magnets that drive magnetic flux across a magnetic airgap formed with a slotless ferromagnetic stator. The stator includes a helical backiron formed from a ferromagnetic strip wound edgewise and extending axially, and an adhesive film on the radial airgap surface of the backiron. Armature windings of wire having individually insulated twisted strands diametrically enveloped by an outer serve are adhered to the adhesive film. The adhesive film holds the said serve to the backiron and the serve holds the strands to the adhesive film. The armature windings pressed into the adhesive film as a group after they are formed and adhered while the adhesive cures, such that the wire is both bonded to the radial airgap surface of the helical stator backiron and is additionally partially embedded in the adhesive film.
