For a bearingless left ventricular assist device, a blood pump is designed and optimized. After principle topology considerations, substantial optimization iterations for the main part a permanent excited axial flux machine are presented. Due to complex magnetic flux tracking, this was mainly proceeded by numerical methods. In addition, in order to feed the drive rotor position dependent, a current converter is designed and developed. Last not least after building prototypes, numerical simulations are validated by substantial measurements. Due to its bearingless approach, the presented drive system offers great ability to realize a long term support.
