摘要： A flywheel device includes an enclosure that surrounds an interior chamber that includes a rotor, which during normal operation is maintained in a vacuum state and spinning, the enclosure includes a first opening, and a valve that attaches to the enclosure, configured to enable, when actuated, ambient air to flow from the exterior of the enclosure into the chamber through the first opening, thus allowing the internal air pressure to rapidly approach ambient air pressure and thereby increase the air drag which acts as a brake on the spinning rotor.

摘要： An apparatus and method for unloading a rotor bearing is described. The apparatus includes an electromagnet for levitating the rotor. In one embodiment, a sensor of the magnetic field near the electromagnet is used to control the current to levitate the rotor. In another embodiment, a method is provided that includes rotating the rotor, increasing the current to levitate the rotor and decrease the gap between electromagnet and rotor, and then reducing the current to levitate the rotor with a minimal amount of electric power to the electromagnet.
