Purpose – The 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/approach – The 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. Findings – The methodology seems to be sufficiently robust, reliable and applicable to a wide spectrum of devices. Research limitations/implications – At this stage of research, the hard-coupled formulation of thermo-mechanical (or thermoelastic) problems is still possible only in 2D. Practical implications – The 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/value – Complete numerical analysis of coupled magneto-thermo-mechanical phenomena in electrical devices. [ABSTRACT FROM AUTHOR]
