Magnetic bearing for water power generator has active magnet repelled from magnetized surface and with field homogenizing layer between

摘要

The magnetic bearing (19) for a water power generator has a support layer (15) with a surface (14) and an active magnet (11) mounted with a gap above the upper surface of the layer. There is a magnetic field magnetizing layer (17) in the gap (12) between the surface and the active magnet. The active magnet can be an electromagnet.
