永磁偏置径向磁轴承的原理分析与参数设计
Principle Analysis and Parameter Design of Permanent Magnet Bias Radial Magnetic Bearing
摘要
Abstract
To overcome the defects of the present permanent magnet biased radial magnetic bearing（PRMB）,a PRMB is studied to develope for the high speed magnetic suspending motor application.The configuration and fundamental principle of PRMB are analyzed.The equivalent magnetic circuit is established to deduce the mathematical model of the radial magnetic suspension force.The displacement stiffness and current stiffness are derived by linearizating the mathematical model.The parameter design of PRMB is presented including the area of magnetic pole,control windings,stator and rotor configuration etc.The parameters of the proposed prototype are given.The 3-D magnetic field simulation is performed,and the static experiment and dynamic experiment are accomplished.The theory analysis and the experiment results show that the rotor hysteresis loss of the presented PRMB is reduced,and it also has smaller volume compared to the existing structure and the control is easier.The levitation performance is well and the parameter design method is rational.关键词
