Abstract

A time-stepping edge element method for the analysis of electric machine transients is presented. A system composed of a permanent magnet motor, voltage inverter and control equipment is considered. The motor windings are represented by filamentary conductors. The mathematical model includes: edge element equations using magnetic vector potential; equations that define the connections of winding and inverter elements; motion equations; and relations that describe the control system. The approach is based on the simultaneous solution of these equations and ungauged edge formulation for the magnetic field. Special attention is paid to the calculation of electromagnetic torque
