Abstract
A device includes a rotor to rotate about a longitudinal axis, a magnetic bearing actuator, and an axial gap generator including a stator assembly adjacent to the rotor, the axial gap generator to generate an amount of power as a function of a gap spacing between the stator assembly and the rotor, the gap spacing parallel to the longitudinal axis, and the axial gap generator to supply the amount of power to a control coil of the magnetic bearing actuator.
Claims29
A device, comprising:
- a rotor configured to rotate about a longitudinal axis;
- a magnetic bearing actuator comprising a control coil positioned adjacent to the rotor and configured to impart a force on the rotor parallel to the longitudinal axis;
- and
- an axial gap generator comprising a stator assembly adjacent to the rotor and electrically connected to the control coil of the magnetic bearing actuator with a wired connection, the axial gap generator configured to generate an amount of power as a function of a gap spacing between the stator assembly and the rotor, the gap spacing parallel to the longitudinal axis, the axial gap generator configured to supply the amount of power to the control coil of the magnetic bearing actuator over the wired connection, where the control coil is a recipient of the amount of power from the axial gap generator.
