Finite Element Analysis of Inductance Parameters for Cylindrical Permanent Magnet Linear Generators Based on Frozen Permeability Method
The frozen permeability method is used as a method to obtain the motor inductance.The direct-axis armature reaction inductance and quadrature-axis armature reaction inductance of the motor are calculated over a wide current range and under load saturation conditions.This ap-proach overcomes the problem of inaccurate inductance parameter calculation due to conventional methods ignoring the effect of cross-saturation.The simulation results provide a theoretical basis for the inductance calculation of cylindrical permanent magnet linear generators.
