摘要

The method of levitation, centering, stabilization and driving of single electromagnetic functional part of radial electromagnetic bearing and electrical rotation drive, which is movable and rotatable in stator (1) of radial electromagnetic bearing through acting of components of magnetic flux, which based on monitoring the position and/or speed and/or acceleration of rotation of electromagnetic functional part of radial electromagnetic bearing and electrical rotation drive induce forces acting upon electromagnetic functional part of radial electromagnetic bearing and electrical rotation drive in axial and/or radial and/or tangential direction. On the electromagnetic functional part of radial electromagnetic bearing and electrical rotation drive being common for radial electromagnetic bearing and electrical rotation drive simultaneously acts stabilizing magnetic flux and driving magnetic flux from separate sources of the magnetic flux. The invention further relates to the electromagnetic bearing and driving system and the spinning mechanism of the rotor spinning machine.
