Abstract

The structure of conical blood pump is introduced, and a new hybrid-type permanent magnetic bearings(PMB) composed of axial and radial PMBs are presented. The hybrid-type PMBs can suspend the rotor in axial and radial directions by the magnetic force. The static magnetic field and the force of PMBs are also computed numerically with the software ANSYS. Study indicates that the radial magnetic suspension force created by the radial bearing is in proportional to the offset of the shaft in radial direction, while the axial magnetic suspension force produced by the radial magnetic bearing do harm to the stability of the bearing in axial direction. Such problem can be solved by reasonable design of the axial and radial magnetic bearings. The research work on PMB provides theoretical basis for the design, optimization and application of conical spiral blood pump.
