Abstract
An illustrative electrostatic machine includes a shaft that is configured to rotate about an axis, a rotor electrode, and a stator electrode. The rotor electrode and the stator electrode are separated by a gap and form a capacitor. The rotor electrode is fixed to the shaft. The electrostatic machine can also include a housing that is configured to enclose the rotor electrode, the stator electrode, and at least a portion of the shaft. The stator electrode is fixed to the housing. A dielectric fluid fills a void defined by the housing, the rotor electrode, and the stator electrode.
Claims20
An electrostatic machine comprising:
- a shaft configured to rotate about an axis;
- a rotor electrode and a stator electrode separated by a gap and forming a capacitor, wherein the rotor electrode is fixed to the shaft;
- a housing configured to enclose the rotor electrode, the stator electrode, and a portion of the shaft, wherein the stator electrode is fixed to the housing;
- and
- a dielectric fluid that fills a void defined by the housing, the rotor electrode, and the stator electrode, wherein the dielectric fluid comprises a compound having a carbonate moiety;
- a nitrile substituted heteroaromatic solvent a compound having a cyclic structure and a moiety represented as —OC(O)N—;
- a fluorinated acyclic hydrocarbon;
- a compound having a sulfonyl group;
- methyl butyrate, γ-butyrolactone, N-methylpyrrolidinone, vinylene carbonate, dioxolane, δ-butyrolactone, diethyl ether, or a mixture of any two or more thereof.
