汽车开关磁阻发电机的磁场分析

Magnetic Field Analysis of a Switched Reluctance Generator Applied in the Automobile

考虑到开关磁阻发电机(SRG)的磁饱和、非线性及磁场疏密分布的情况,通过ANSYS软件进行了在不同转子位置、不同电流下的SRG磁场的二维有限元分析和计算,据此可求得电机的参数和性能,并为实现电机的进一步优化做好基础。

With the consideration of the magnetic saturation , nonlinearity and magnetic field's distribution of the switched reluctance generator(SRG),the paper, by the software of ANSYS, makes the magnetic field of the SRG with arbitrary rotor's position angle and phase current value be analyzed and calculated by finite element method. On the basis of this, we can obtain the motor's parameters and performance, and prepare for realizing the motor's further optimal design.
