Claim 14:
15. A blood pump system comprising:
a blood pump, the blood pump further including a delivery element and a magnetic bearing, the magnetic bearing comprising a permanent magnet, a first coil, and a second coil, wherein the second coil is configured to cause an oscillation of the delivery element by generation of a thrust force against the delivery element, the thrust force caused by an application of an excitation signal to the second coil, and wherein the first coil of the magnetic bearing is configured to apply a counter-force against the thrust force;
a control device configured to stabilize the position of the delivery element by control of current through the first and second coils, the control device also configured to cause the application of the excitation signal to the second coil for excitation of the oscillation of the delivery element; and
a sensor configured to detect a measurement of an oscillation behaviour the delivery element.
