Claim Text:
1. A magnetic radial bearing, comprising: a stator comprising a first coil, a second coil, a third coil arranged opposite the first coil and a fourth coil arranged opposite the second coil, wherein the first and third coils are disposed on a first axis and the second and fourth coils are disposed on a second axis, and wherein first terminals of the first, second, third and fourth coils are connected to a first phase of a 3-phase current, second terminals of the third and fourth coils are connected to a second phase of the 3-phase current, and second terminals of the first and second coils are connected to a third phase of the 3-phase current, and a control device for controlling the coils of the stator by applying to each phase of the 3-phase current a respective sinusoidal current that is phase-shifted relative to a current of another phase of the 3-phase current by 120°, wherein the control device controls each of the first and second axes at a variable operating point, with the variable operating point defining amplitudes of the respective sinusoidal current of each of the phases of the 3-phase current.
