Resumo(s)
This paper deals with the design process of electric machines,
proposing a design flowchart which couples the electromagnetic and
thermal models of the machine, assisted by finite element techniques. The
optimization of an electrical machine, in terms of the energy efficiency and
cost reduction requirements, benefits from the coupling design of the
electromagnetic and thermal models. It allows the maximization of the
current density and, consequently, the torque/power density within thermal
limits of the active materials. The proposed coupled electromagneticthermal
analysis is demonstrated using a single-phase transformer of 1
kVA. Finite element analysis is carried out via ANSYS Workbench, using
Maxwell 3D for the electromagnetic design, with resistive and iron losses
directly coupled to a steady-state thermal simulation, in order to determine
the temperature rise which, in turn, returns to electromagnetic model for
material properties update.
