Engineering often requires magnetic bearings with sufficient capacity and to reduce the volume as much as possible at the same time. In this paper, the design principles of air gap, magnetic pole, rotor, stator, magnetic pole area and coils are given on the basis of practical engineering experience. Radial magnetic bearing structure with different shaft diameters and different magnetic poles number...
Strain localization influenced by microstructural features has an important effect on mechanical properties of α+β titanium alloy. To address the effect, a microstructure-based finite element model is established. In this model, regions for primary α (αp) and transformed β matrix (βt) are generated from real microstructures of a two-phase titanium alloy (TA15 alloy); the plastic flow behaviors of...
In this paper, the shells of internal gear pumps of different materials were analyzed by ANSYS software to find the different applications between shells of dectile iron and shells of aluminum. Then, these two kinds of shells were optimized, which improved the overall performance of the gear pumps. Finally, the actual deformation of shells of gear punps under different loads were measured. And the...
This paper describes a newly developed position sensor system. The position sensing system is designed to be combined with the radial permanent magnetic bearing and used for the control of the axial active magnetic bearing. The rotor ring of the radial magnetic bearing is used as field source, which shortens the rotor and saves space for artificial heart design. Linear hall sensor is selected due...
