WOUND FIELD ROTATING MACHINE WITH CAPACITIVE POWER TRANSFER

摘要

An electrical rotating machine, such as a generator or motor, communicates power from a stationary location to the rotating rotor of the rotating machine via opposed pairs of capacitor plates, one plate of each pair rotating with the rotor and one plate of each pair fixed not to rotate. In one embodiment, separation between the plates of the pair is provided by a cushion of entrapped air.

主权项

1. An electrical rotating machine comprising:
a rotor mounted for rotation about an axis and including at least one electrical coil having a coil axis with a component perpendicular to the axis, the electrical coil comprising a conductor having first and second conductor ends; at least one first capacitor plate, attached to rotate with the rotor and electrically communicating with the rotor; and at least one second capacitor plate, mounted to a frame so as not to rotate with the rotor and positioned for capacitive coupling with the first capacitor plate; wherein the first and second capacitor plates are positioned to transfer power between the electrical coil and a stationary conductor at a range of angular positions of the rotor about the axis.
