The invasive model of power supply for the commercial blood pumps has brought great discomfort to the patients. An inductive power transmission system based on transformer for blood pumps has been designed and developed. The system is mainly consist of power supply, control circuit of switch, transformer, rectifier circuit and energy storage element.(More)
Three passive magnetic bearings developed by the authors have been applied to the impeller blood pumps. The measuring system with hall sensors is built for determination of the maximal rotor eccentric distances in the pumps. The results show that when the rotating speed exceeds 4000rpm and the mass flow rate exceed 4 L/min, magnetic levitations can be(More)
