Abstract: Embodiments of the subject invention are directed to a homopolar motor and its mechanical coupling with a flywheel rotor. The homopolar motor includes a rotor and no additional bearings, shafts, gears, pulleys, etc., are required to couple the the flywheel rotor and the rotor of the homopolar motor. The homopolar motor includes a stator with a stator laminate and a number of stator pole pieces. The pole pieces generate magnetic flux across a first radial gap to rotor assembly to generate torque. Rotor assembly is coupled to and rotates with shaft which in turn rotates the flywheel rotor. The rotor assembly includes a rotor laminate stack and a field coupler. The field coupler has a top portion that rotates with the shaft and a bottom portion that attaches to a housing and remains stationary.
