Electrical bearing drive for e.g. powered vehicle on street, has rotor/rim rotated around stator/shaft that has primary parts including permanent magnets, where magnetic forces are electromagnetic, dynamic or permanent magnetic forces

摘要

The drive has a rotor/rim rotated around a stator/shaft that has primary parts (P11-P32) having permanent magnets, where the rotor/rim has secondary parts (S1, S2). A guide-controller of sequence-controllers of the individual primary parts provides a threshold value, such that an optimal gap distance and a threshold value of speed are obtained and kept, where magnetic forces are electromagnetic, dynamic or permanent magnetic forces.
