Abstract

The paper presents analytic design of active magnetic bearing PM synchronous motor for TAH (Total Artificial Heart) application and description of the drive and levitation electromagnet control. Pump system is double ventricle blood pump consisting of slotless PM axial flux synchronous machine and magnetic active bearings. The general electric machine theory is applied to the motor design. Power quality is ensured by the help of the rare earth PM and for good torque quality is used slotless, three phase winding and surface mounting PM. Control part deals with the synchronous motor and magnetic bearing control. Two structures, voltage and current, were design and tested for the position regulation. Mathematical model was successfully simulated. On the base of this model the regulation structure for positional feedback control was design. Design of the regulators is based on the mathematical model description of controlled system.
