Computerized analysis of magnetically coupled electromechanical systems

An efficient, flexible method for evaluating flux-current-force-position relationships in nonlinear magnetically coupled electromechanical systems is described. Given these relationships, the system differential equations may be solved simply under the control of a differential equation solving program such as digital simulation language-360 (DSL-360). The method starts from a description of the system in primary physical terms (such as geometric dimensions, magnetization curves, external mechanical forces, voltage, etc.), computes the system magnetic fluxes, field energy, and forces, while simultaneously proceeding through a differential equation solution to produce a description of system performance. Unless great care is exercised when programming the problem, excessive digital computer execution could be required. A particularly valuable feature of this method is the efficiency with which the total problem solution is obtained.
