Abstract
In one embodiment, a generator includes a rotor configured to rotate in cooperation with a stator to generate electrical power. An exciter of the generator includes at least one circuit board, a stationary exciter stator, and a control circuit. The circuit board is mechanically coupled to a rotor of the generator and includes at least one coil of an electrical conductor. The stationary exciter stator is configured to induce a current in the at least one coil of the at least one circuit board. The control circuit is configured to modify the current from the at least one coil and provide the modified current to a field of the generator.
Claims20
An exciter for a generator, the exciter comprising:
- at least one circuit board mechanically coupled to a rotor of the generator, the circuit board including at least one coil of an electrical conductor;
- a stationary exciter stator configured to induce a current in the at least one coil of the at least one circuit board;
- and
- a control circuit included in the at least one circuit board, the control circuit configured to modify the current from the at least one coil and provide the modified current to a field of the generator.
A generator comprising:
- a rotating assembly;
- a generator controller configured to rotate with the rotating assembly;
- and
- a circuit board configured to rotate with the rotating assembly and including a first set of traces electrically connected to the generator controller and a second set of traces configured to induce a field current.
A method for axially positioning a printed circuit board connected to a rotating shaft, the method comprising:
- supporting a printed circuit board to be movable in a direction parallel to the rotating shaft while maintaining a rotational connection to the rotating shaft;
- and
- adjusting a position of the printed circuit board relative to the rotating shaft.
