摘　　要：磁悬浮无轴承电机是集驱动与自悬浮功能于一体的新型电机。与传统的磁悬浮电机相比,不需要配备占有相当轴向空间的径向磁悬浮轴承,因而其体积和重量大为减少,而临界转速大幅度提高,可突破大功率和微型化应用领域的限制。介绍了磁悬浮无轴承电机悬浮控制的基本原理,设计出了两种不同磁场定向的悬浮控制系统的数学模型。Magnetic Suspension bearingless motor is the new electrical machinery that combines actuation and the aerosol function in a body. Comparing the traditional magnetism aerosol motor, it does not need providing the quite large axial spatial radial direction magnetism aerosol bearing, thus its volume and weight greatly reduce. But the critical rotation speeds large scale enhancement, may break the high efficiency and the microminiaturized application domain limit. The paper introduced the basic principle of the magnetic Suspension bearingless motor aerosol control, control system math models were designed based on the two different magnetic field direction detection aerosol.
