    "concept_summary": "A rotating AC generator with a hollow stator core, a cylindrical rotor, two sets of magnets (north-facing and south-facing) mounted on the rotor, and silicon-steel pieces positioned adjacent to each magnet. The stator contains longitudinally laminated high-permeability steel sheets with slots for a conductor winding. The arrangement is intended to reduce the reaction (back torque) on the rotor, improving overall efficiency.",
