In this paper a two-dimensional transient thermal model of the rotor of an induction motor during star-delta starting is presented using finite element formulation and arch-shaped elements. Excepting for providing a more accurate representation of the problem, the proposed model can also reduce computing costs. A temperature-time method is employed to evaluate the distribution of loss in various parts...
In developing electric motors in general and induction motors in particular temperature limits are a key factor affecting the efficiency of the overall design. Since conventional loading of induction motors is often expensive, the estimation of temperature rise by tools of mathematical modeling becomes increasingly important. Excepting for providing a more accurate representation of the problem, the...
