Abstract
An electric machine for converting between electrical and rotary mechanical energy includes a rotor journaled to rotate about an axis of rotation, and a stationary stator mounted adjacent to the rotor. The stator has a ferromagnetic backiron with a surface facing the rotor across a magnetic airgap and having windings applied in a winding pattern formed directly onto the stator backiron and adhered to its surface with a pre-applied tacky adhesive. The windings magnetically exert torque upon the rotor across the magnetic armature airgap in response to electric power applied to the windings. The rotor has permanent magnets that generate magnetic flux across the airgap and through the windings. The windings are comprised of pre-bundled multiple individually insulated conductor strands that are electrically connected in parallel but are electrically insulated from each other along their lengths inside said magnetic armature airgap.
