A novel centrifugal pump has been developed that employs a bearingless motor with two-axis radial active positioning control. The structure of this motor is an extension of a hybrid of consequent-pole and homopolar-type bearingless motors. The passive stiffness has been enhanced. The test pump was fabricated and found to provide a maximum pump output of 1 W with a flow rate of 4 L/min against a head...
In order to improve rotor-impeller suspension performance of the developing ventricular assist device, axial magnetic bearing with various permanent magnet arrangements are designed and fabricated. Separate permanent magnets type stator shows wide linear range and improved force characteristics.
This paper presented a prototype axial blood pump with a single-axis controlled magnetic bearing. The magnetic suspension system is realized by using passive magnetic bearings for radial direction balancing, and an electromagnetic actuator to stabilize the axial direction actively. A sensor assembly for axial position sensing is also presented. This sensor can measure axial position with good accuracy...
