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 a number of permanent magnets, which produce an attracting force of an expulsing force between the rotor and the stator.
