  • Patent number: 11509175
    Abstract: A homopolar multi-core energy conversion device is an apparatus that uses magnetic flux commutation instead of a combination of electrical current commutation and brushes. The apparatus includes a first discontinuous annular stator core, a second discontinuous annular stator core, and a rotor core. The first discontinuous annular stator core is configured to generate a circumferentially-segmented clockwise magnetic flux around the rotor core, while second discontinuous annular stator core is configured to generate a circumferentially-segmented counter-clockwise magnetic flux around the rotor core. The rotor core is configured to radially partition a traversing magnetic flux. The circumferentially-segmented clockwise magnetic flux, the circumferentially-segmented counter-clockwise magnetic flux, and the traversing magnetic flux interact with each other so that the apparatus can function either as a motor or as a generator.
