| 摘 要： | 介绍了无轴承电机工作原理,以附加二极悬浮力绕组的四极无轴承电机为研究对象,建立适用于圆柱型和凸极型转子的无轴承电机的通用电感矩阵模型,进而推导出径向悬浮力通用数学模型.基于该数学模型,以无轴承同步磁阻电机和无轴承永磁同步电机为例,得出径向悬浮力公式和径向悬浮力计算值,并分别与用ANSYS有限元分析软件计算的径向悬浮力数值进行对比.模型计算结果与ANSYS分析结果基本吻合,该径向悬浮力数学模型的正确性得到验证.

| Abstract: | The working principle of bearingless motors was introduced.The general expressions of the inductances were established for bearingless motors with the column rotor or the gibbose-pole rotor.The mathematic model of radial suspension forces was deduced for the bearingless motors with conventional 4-pole stator windings and additional 2-pole suspension force windings.Based on the radial suspension force mathematic model,taking a bearingless synchronous reluctance motor and a bearingless permanent magnet synchronous motor for examples,corresponding suspension force formula was deduced.The calculated results for the suspension force agree with the results calculated with finite element method(FEM) software. |
