摘要

In this paper, we introduce the property and effects of using magnetic bearings for the synchronous magnetic axial coupling operation of magnetic wireless pumps. Typically, the developed magnetic wireless pump can be driven by both synchronous radial and axial coupling. However, because of the radial direction of magnetization in the fully magnetic impeller and the strong coupling force, synchronous magnetic radial coupling has been used for magnetic wireless pumps. To utilize a synchronous axial coupling with weaker coupling force to driving the pump, we considered a magnetic bearing mechanism using the magnetic array of rectangular Nd-Fe-B magnets (14 pieces). The proposed magnetic bearing resulted in a magnetically levitated effect, stable operation, and wide torque variation in the magnetic axial coupling. We investigated the magnetic properties and the enhanced driving performance of the magnetic wireless pump through simulation with experiments.
