“…These lumped models of iron loss are useful but do not allow iron loss to be studied in detail. Some studies have specifically addressed losses arising from inverter supply [15,16] but are limited in nature. There are models for iron loss in thin laminations [12,13,17], which determination provide loss density results for a localized flux density expressed as a function of time.…”

This paper is concerned with the effect of power system harmonics and voltage unbalances on the thermal aging of the insulation of electric motors. A thermal model is proposed where the motor is divided geometrically into a number of lumped components, with interconnections to neighboring components through a linear mesh of thermal impedances. The lumped parameters are derived from entirely dimensional information, the thermal properties of the materials used, and constant heat transfer coefficients. Arrhenius chart is then used to estimate motor insulation remaining life. The proposed approach is used to determine the effect of supply harmonics and voltage unbalances on the useful life of a three phase induction motor and also validated by experimental results.
