The aim of this article is modeling, simulation, control and complex design of Active Magnetic Levitation Systems (AMLS). In this application is necessary to proposed the effective control law for the stable operation in levitation mode because these devices in nature are essentially unstable. The stabilizing controller has to generate the appropriate value of electromagnetic force to levitate an...
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.
