Automated Python-Controlled Thermal Analysis of Rotor of Line-Start Permanent Magnet Synchronous Machine

Abstract

—This paper deals with the thermal analysis of the rotor of the line-start permanent magnet synchronous machine (LSPMSM). First, a concept of a fully controlled parametric geometry creation using the Python programming language is introduced. The geometry is created using the FreeCAD software. Afterwards, the geometry is used to perform a thermal analysis using the finite element method (FEM) in the Ansys Workbench Software. This analysis is also controlled by Python. A thermal model of the analyzed rotor was also created using lumped parameter thermal network (LPTN). Finally, the resulting temperatures from the FEM-based analysis are used to verify the functionality of the lumped-parameter thermal network.
