Passive magnetic bearing for high-speed applications
Traditional bearings are a limiting factor to high-speed applications. Nowadays, active magnetic bearings are available, but due to their price and their complexity, they remain a last resort solution.
The UCL invention
This invented bearing is a fully passive magnetic bearing, stable when spinning at room-temperature. It gathers the benefits from active magnetic bearings, i.e. contactless operation, and the benefits from a passive device, which means a simpler, cheaper and intrinsically stable device. The invention is based on the null-flux principle, which means there are no losses in nominal operation, when centered.
- High-speed motors
- Vacuum pumps
- Contact free bearing
- Easy-to-use and to implement
- Low losses and superior lifetime
- No need for active control
- No need for cryogenic cooling
- Easy integration in permanent magnet motors
TRL 2 Theoretical developments give us a complete toolbox to predict static and dynamic performances of the bearing.
Shortly, a prototype showing the working principle will be operating.
