摘要

摘要: 立式电机通常利用混合型轴向磁悬浮轴承对轴向进行卸载和悬浮控制,由于混合型轴向磁轴承中永磁体与控制绕组的结构分布影响其悬浮控制性能,因此需要从偏置和控制磁场的角度对其进行结构设计。分析了一种用于立式电机的新型单边混合型轴向磁悬浮轴承的结构和工作原理,并从电磁场理论计算出发,借鉴电机设计方法,提出了一种以偏置磁场与控制磁场的磁场比为约束条件,动静态承载荷、悬浮刚度为目标进行参数设计。最后通过Maxwell有限元仿真验证了参数设计方法的合理性与有效性。

Abstract: Usually a vertical motor uses hybrid axial magnetic bearings to carry out unloading and suspension control due to the structure of a permanent magnet and the influence of a hybrid axial magnetic bearing's control winding distribution on suspension performance, requiring the structural design according to bias and control magnetic field. This paper first analyzes the structure and working principles of a new single-side hybrid axial magnetic bearing used in the vertical motor. Then, according to the electromagnetic field measurement theory and the design method of the vertical motor, we present a parameter design method based on the bias/control magnetic field ratio restrictions. Finally we use the FEA software to verify the rationality and effectiveness of the parameter design method and to achieve the static/dynamic load and suspension stiffness.
