Abstract: Rotary capacitor assemblies divert or mitigate high-frequericy electrical currents and voltages in bearings of electric machinery (e.g., motors and generators) without direct contact with the bearings. The assemblies include rotating capacitors, in which surfaces in close proximity are free to rotate with respect to another while maintaining relative surface area and separation distance. A lubricant (such as air or oil) facilitates capacitive surfaces hydrodynamically "floating" on each other. A shunt body is connected electrically in parallel with the bearings of the machine, providing a non-contact or nearly non-contact electrical pathway for damaging high-frequency currents an voltages to be shunted around the mechanical load carrying bearings.
