Lumped parameter thermal network (LPTN) is widely used for calculation the temperature rise in electrical machines. In LPTN models, heat transfer process in the motor are abstracted form a thermal point of view and can be described via equivalent circuit diagrams, the thermal capacity is modeled by means of a capacitor, as used for describing electric circuits. Compared to the numerical method such as Finite-Element Method (FEM) and Finite-Volume Method (FVM), lumped parameter modeling requires less calculation time and easy to parameter optimization, especially for 3D modeling and dynamic simulation.@en
