Field‐circuit model of the dynamics of electromechanical device 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.
