Axisymmetric electromagnetic field simulation based on coordinate transformed auxiliary potential
The coordinate transformation auxiliary potential method for axisymmetric static magnetic field is promoted and applied to finite element analysis of axisymmetric electromagnetic fields including twisted coil,nonlinear magnetic permeability iron core,external circuit,and motion coupling.The method is implemented using domestic low-frequency electromagnetic simulation software INTESIM-Emag programming.Numerical examples show that the technical solution based on coordinate transformation assisted potential method can achieve high computational accuracy.The dynamic performance simulation of a certain axisymmetric electromagnetic valve proves the applicability and accuracy of this scheme for engineering problem simulation.
