1. A homopolar motor-generator comprising:
a core assembly includes a motor-generator stator with a plurality of stator rings arranged about a central axis; a field coil interposed between adjacent stator rings encircles the central axis; armature coils interengage aligned peripheral slots of the stator rings, have axially spaced end turns to either side of the stator, and do not encircle the central axis; a motor-generator rotor in the form of an elongated cylinder encircles and is coaxial with the stator; and, the rotor includes plural rotor segments arranged along its length and plural rotor segments arranged circumferentially, the rotor segments arranged to form a lattice with lattice openings; wherein each rotor segment provides a staggered magnetic path for completing a magnetic circuit interconnecting adjacent stator rings.
