Field-circuit model of the dynamics of electromechanical device supplied supplied by electronic power converters

This paper presents a coupled field-circuit simulation of transients in a non-linear electromagnetic device supplied by electronic power converters (inverters, PWM systems). The eddy currents induced in solid cores are considered The mathematical model of transients includes: equation of electromagnetic field, equations of the electric circuits and equation of motion. Numerical implementation of the algorithm is based on the finite element method. For time-stepping the Cranck-Nicholson scheme has been applied.
