摘要
针对双绕组无轴承开关磁阻电机的绕组结构复杂、绝缘程度要求高及加工成本高的缺陷,结合悬浮原理和磁阻最小原理,提出一种磁悬浮开关磁阻球体电机.分析了磁悬浮开关磁阻球体电机的基本组成和运行机理,采用磁路分割法对各部分磁路进行推导与计算,建立了球体电机的数学模型.利用Matalab/simunik软件进行仿真,结果表明电机能够实现动子快速稳定悬浮和旋转,并且具有良好的抗干扰性能.
In view of the bearingless switched reluctance motor with double windings,which has a complicated structure,an absolute insulation,and expensive manufacture cost,the paper presents a spherical switched reluctance motor with magnetic levitation on the basis of suspension theory and minimum reluctance principle.It analyses elements and machanism of the spherical switched reluctance motor with magnetic levitation,deduces and calculates the magnetic conduction of the gap by means of the magnetic segmentation.It obtaines a model building of spherical electric machines.with the Matalab/simunik model,simulation results show that the rotor realizes quick stable suspension and rotation,it has excellent anti-jamming performance as well.
