摘要： Permanent magnet bearings are incorporated into rotating equipment, such as induction machines, in addition to active magnetic or lubricated primary shaft support bearings. The passive magnetic bearings incorporate permanent magnets that generate directionally oriented magnetic fields of selective intensity. The magnetic field directions are aligned with a desired shaft support bearing preload direction and intensity, for example to exert axial thrust or radial preloads on the support bearings. A plurality of magnetic bearings may be oriented in opposed relationship with neutral or offsetting resultant forces. The passive magnetic force preload may be utilized to offset rotor vertical weight during induction startup or stopping cycles. Passive magnetic force preload may be applied to lubricated bearings to assure their operational stability. The passive magnetic bearings can also absorb radial or axial thrust forces imparted on the rotor shaft during induction machine operation, that may reduce machine operational noise, and energy consumption.

摘要： A flywheel energy storage system includes an energy storage flywheel supported on a bearing system for rotation about a substantially vertical axis inside in an evacuated chamber enclosed within a sealed container. A motor and a generator accelerates and decelerates the flywheel for storing and retrieving energy. A tilt sensor detects if the orientation of the axis of rotation is outside of tolerance limits from vertical and triggers a signal to signal appropriate system functions to protect the system from damage.

摘要： The invention relates to a bearing, which comprises at least two groups radial stable magnetic rings and at least one group axial stable magnetic ring designed between the radial stable magnetic rings. The radial stable magnetic ring consists of a radial static magnetic ring fixed to a bearing housing and a radial movable magnetic ring which is parallel to the radial static magnetic ring and fixed to a shaft sleeve extends in the radial direction. Both the radial static magnetic ring and the radial movable magnetic ring are composed of more than two cross magnetic poles that are closely connected in the radial direction. The structure of the axial stable magnetic ring designed axially is the same as this of the radial stable magnetic ring. The invention is of simple design and large power.
