Numerical simulation of electrical engineering devices

Abstract

PurposeThe paper seeks to present a methodology of computer simulation of coupled magneto‐thermo‐mechanical processes in various electrical engineering devices. The methodology allows determining their parameters, characteristics and behaviour in various operation regimes.Design/methodology/approachThe mathematical model consisting of three equations describing magnetic field, temperature field and field of mechanical strains and stresses (or thermoelastic displacements) is solved numerically, partially in the hard‐coupled formulation.FindingsThe methodology seems to be sufficiently robust, reliable and applicable to a wide spectrum of devices.Research limitations/implicationsAt this stage of research, the hard‐coupled formulation of thermo‐mechanical (or thermoelastic) problems is still possible only in 2D.Practical implicationsThe methodology can successfully be used for design of numerous machines, apparatus and devices from the area of low‐frequency electrical engineering ranging from small actuators to large synchronous generators.Originality/valueComplete numerical analysis of coupled magneto‐thermo‐mechanical phenomena in electrical devices.
