Abstract
The present invention provides a device and a method to enhance thrust load capacity in a rotor-bearing system. The load-enhancing device comprises a stator and a rotor arranged in such as way as to achieve a magnetic thrust load capacity enhancement by employing at least one permanent magnet, which produces an attracting force or an expulsing force between the rotor and the stator.
