提出了一种新型的无轴承盘式电机，并将其应用于植入式离心式人工心脏。为了减小电动机高度，采用具有径向扩展线圈绕组的C形定子芯。端部绕组不位于轴向方向。电机高度和外径分别设计为10 mm和70 mm。采用有限元法对盘式无轴承电机的磁悬浮特性进行了分析。特别讨论了径向悬浮力变化对悬浮绕组结构设计的影响。制造并测试了样机。实验结果为无轴承盘式电机的设计提供了可行性。
A novel bearingless disk motor for a possible application of implantable centrifugal artificial hearts is proposed in this paper. To reduce a motor height, C-shaped stator cores with radially expanded coil windings are employed. End windings are not located in the axial direction. The motor height and an outer diameter are designed to be 10mm and 70mm, respectively. Magnetic suspension characteristics of the bearingless disk motor are analyzed by using finite element method. The design consideration of a suspension winding configuration has been discussed especially on radial suspension force variations. A prototype machine is fabricated and tested. Experimental results have provided the feasibility of the design of the bearingless disk motor.
