| 81 | Device for detecting an unbalance in a rotor of a centrifuge | US8683 | 1998-01-16 | US6062078A | 2000-05-16 | Artur Meisberger |
| The invention relates to an unbalance detector, such as for a centrifuge. The invention preferably comprises a pressure-sensitive static sensor, preferably in the form of a piezoelectric cable, which preferably is mounted on a stationary casing part and delivers an imbalance signal when it comes in mechanical contact with the rotor which has been deflected because of an imbalance. As an alternative, the sensor can also be mounted on the rotor and deliver the unbalance signal on coming in mechanical contact with the stationary casing part. According to another embodiment of the invention, the analysis stage for the unbalance signal has a test stage or simulation stage for testing the functionality of the unbalance detector. | ||||||

| A flywheel energy storage system incorporates various embodiments in design and processing to achieve a very high ratio of energy stored per unit cost. The system uses a high-strength steel rotor rotating in a vacuum envelope. The rotor has a geometry that ensures high yield strength throughout its cross-section using various low-cost quenched and tempered alloy steels. Low-cost is also achieved by forging the rotor in a single piece with integral shafts. A high energy density is achieved with adequate safety margins through a pre-conditioning treatment. The bearing and suspension system utilizes an electromagnet that off-loads the rotor allowing for the use of low-cost, conventional rolling contact bearings over an operating lifetime of several years. | ||||||
