| 摘 要： | 针对两极平行充磁实心圆柱式永磁同步电机(SCPMSM),分析转子偏心对气隙磁场空间和频率特性的影响。通过引入转子静态偏心和动态偏心磁导修正系数,建立了转子偏心气隙磁场的数学模型,分析了空载和负载情形下转子静态偏心以及动态偏心气隙磁场的空间和频率特性。以1台2极12槽SCPMSM为例,对转子偏心气隙磁场特性进行了有限元分析,验证了理论分析的正确性。

| Abstract: | The twopole parallelly magnetized solid cylindrical permanent magnet synchronous motor (SCPMSM) was taken as the study object and the effects of rotor eccentricity on spatial and frequency characteristics of airgap magnetic field were analyzed. Introducing the airgap permeance correction factors of rotor static and dynamic eccentricities, the mathematical models of the airgap magnetic fields in the SCPMSM with rotor eccentricity were developed. The spatial and frequency characteristics of airgap magnetic fields under both static and dynamic rotor eccentricity modes in noload and load cases were analyzed. Taking a 2pole 12slot parallelly magnetised SCPMSM as example, the characteristics of rotor eccentric airgap magnetic fields were analyzed by the finite element method, which verified the correctness of the theoretical analysis. |
