An inductor-alternator provides highly efficient conversion between mechanical and electrical energy. The inductor-alternator produces increased output by providing armature coils in a single air gap formed between two halves of a toothed rotor. In preferred embodiments, field coils of a magnetic circuit are energized with DC drive current that creates homopolar flux within the rotating rotor. Airgap armature coils are mounted with the field coils to form a stationary assembly that is placed within the single air gap in the rotor so that the changing flux density (due to the rotating teeth) induces an output voltage in the armature coils. The rotor and stationary assembly are mounted in a housing by bolts that may also be used as terminals for the armature coils to reduce assembly complexity and production cost. The combined assembly provides high energy and power density because tip speed of the rotor is maximized and the use of air gaps is minimized.
