This work describes a new technique for the induction machine analysis using finite element method. It is based on magneto-static simulations, in which both stator and rotor current are imposed as field sources. The rotor current is set in the bars using an equivalent poly-phase winding and the amplitude is derived the main concepts of the machine analytical model in the rotor field oriented reference frame. The main part of the work is the comparison with the time-domain analysis results, considered to be the benchmark, as a very accurate and exhaustive approach. The great advantage of using the new method, based on the magneto-static finite element formulation, is the dramatic reduction of the computation time, for deriving steady-state machine performance.

Abstract

This work describes a new technique for the induction machine analysis using finite element method. It is based on magneto-static simulations, in which both stator and rotor current are imposed as field sources. The rotor current is set in the bars using an equivalent poly-phase winding and the amplitude is derived the main concepts of the machine analytical model in the rotor field oriented reference frame. The main part of the work is the comparison with the time-domain analysis results, considered to be the benchmark, as a very accurate and exhaustive approach. The great advantage of using the new method, based on the magneto-static finite element formulation, is the dramatic reduction of the computation time, for deriving steady-state machine performance.
