Abstract
Flywheel systems with multiple generator coils are provided with a rotor disk configured to rotate about a rotational axis; a plurality of magnets disposed in the rotor disk, the plurality of magnets angularly distributed around the rotational axis, and the plurality of magnets magnetically aligned such that respective magnetic north poles of each magnet of the plurality of magnets face a same direction; and a coil disposed adjacent to the rotor disk, the coil extending axially away from the rotor disk, and the coil positioned to sequentially overlap each magnet of the plurality of magnets in response to rotation of the rotor disk about the rotational axis.
Claims21
A device comprising:
- a rotor disk configured to rotate about a rotational axis;
- a plurality of magnets disposed in the rotor disk, the plurality of magnets angularly distributed around the rotational axis;
- and
- a coil disposed adjacent to the rotor disk, the coil extending axially away from the rotor disk, and the coil positioned to sequentially overlap each magnet of the plurality of magnets in response to rotation of the rotor disk about the rotational axis, wherein the coil is positioned to overlap with a single magnet of the plurality of magnets on the rotor disk at any given time to be within a magnetic gap threshold of the one single magnet.
A system comprising:
- one or more rotor disks configured to rotate about a rotational axis, wherein each of the one or more rotor disks includes a respective plurality of magnets angularly distributed about the rotational axis;
- a plurality of coils, each respective coil of the plurality of coils positioned to overlap with a single magnet of the plurality of magnets on a respective rotor disk of the one or more rotor disks at any given time to be within a magnetic gap threshold of the single magnet, the respective coil extending axially from a proximal end of the respective coil facing the respective disk to a distal end of the respective coil opposite the proximal end in a direction parallel to the rotational axis;
- a load bus configured to transport electrical power;
- a plurality of switches, each of the plurality of switches having a respective switch output that is electrically connected to the load bus;
- and
- a controller coupled to the plurality of switches and configured to selectively connect at least one of the plurality of coils to the load bus by operating the plurality of switches.
A system, comprising:
- a plurality of rotor disks, including:
- a first rotor disk including a first plurality of magnets angularly distributed relative to a rotation axis;
- a second rotor disk including a second plurality of magnets angularly distributed relative to the rotation axis;
- a plurality of coils, including:
- a first coil positioned to be within a magnetic gap distance of each magnet of the first plurality of magnets, wherein the first coil is positioned to overlap with a single magnet of the first plurality of magnets on the first rotor disk at any given time to be within the magnetic gap threshold of the single magnet of the first plurality of magnets;
- and
- a second coil positioned to be within the magnetic gap distance of each magnetic of the second plurality of magnets, wherein second first coil is positioned to overlap with a single magnet of the second plurality of magnets on the second rotor disk at any given time to be within the magnetic gap threshold of the single magnet of the first plurality of magnets;
- and
- wherein the first rotor disk and the first coil are positioned relative to the second rotor disk and the second coil to sequentially overlap the first plurality of magnets with the first coil relative to overlapping the second plurality of magnets with the second coil while rotating the first rotor disk and the second rotor disk at shared rotational speed about the rotation axis.
