Low-Cost Minimal-Loss Flywheel Battery
InactiveUS20100283340A1Low-cost minimal-lossMinimize ball bearing radial thrustRolling contact bearingsControllers with pulse-train output signalBall bearingDc current
A low-cost minimal-loss zero-maintenance flywheel battery, to store electric power from a DC power source by conversion to kinetic energy, and regenerate electric power as needed. Its vertical spin-axis rotor assembly is supported axially by repelling annular permanent magnets, and is centered by ceramic ball bearings which have axial preload that prevents vibration and augments axial rotor support. A regenerative multi-pole permanent-magnet motor, controlled by its 2-phase stator current, and connected by power and signal conductors to power interface electronics, is integrated within the flywheel assembly, in a vacuum enclosure supported by a self-leveling structure. Sinusoidal 2-phase stator currents are controlled by high-frequency pulse-width-modulated H-bridge power electronics that draw and regenerate controlled DC current with minimal ripple, responsive to respective 2-phase rotation angle sensors, the DC power voltage, and other settings. The electronics includes logic and over-voltage protection to prevent otherwise possible damaging current and voltage.

According to the stainless steel composite pipeline, the defect that a stainless steel pipe cannot be directly buried is well overcome, the price of the pipeline is lower than that of a common stainless steel pipeline and equivalent to that of thin-wall stainless steel, the pressure bearing performance is consistent withthat of the common stainless steel pipeline and a lining stainless steel pipeline and higher than that of a thin-wall stainless steel pipeline, the comprehensive cost performance is high, and the pipeline is worthy of popularization and application.
