ABSTRACT:
A multipole homopolar inductor motor/alternator for a flywheel drive includes a rotor assembly on the outside of the stator which functions as the flywheel. Locating the excitation field winding on the stator between two stacks of stator laminations enables the rotor assembly to be operated at much higher temperatures than a wound rotor, without detrimental effect on overall efficiency. The rotor assembly is also operable at much higher speeds than would be possible if the rotor were wound, resulting in apparatus better adapted to store energy mechanically.
