Analysis Type(s): Nonlinear Magnetic Static Analysis (ANTYPE = 0) Element Type(s): 3-D 20-Node Magnetic Solid Elements (SOLID117) Input Listing: vm221.dat Figure 221.1 Representative Finite Element Model Test Case A transformer with a nonlinear iron core is wound with two separate coils. Coil 1 is excited by a current of 0.2 A, while coil 2 is excited by a small current of 0.025 A. Calculate the self-inductance of both coil 1 and coil 2, and also the mutual inductance between the two coils. Material Properties B = Bs H Hs where BS = 2T andHS = 100A / m Geometric Properties X = X1 = X2 = Y = Z = 0.015m N1 = 10 (number of turns in coil 1) N2 = 20 (number of turns in coil 2) Loading I1 = 0.2A (applied current in coil 1) I2 = 0.025A (applied current in coil 2) Analysis Assumptions and Modeling Notes In this problem the LMATRIX macro is used to solve the coil inductance about an operating point (I1, I2). The finite element representation is modeled by three blocks, coi...
