On the Usefulness of Employing ANSYS Motor-CAD Software in Designing Permanent Magnet Synchronous Machines

Abstract

This paper deals with the simulation of a permanent magnet synchronous machine (PMSM) to be developed for driving a scroll compressor of a vehicle air conditioning system. The simulations were needed for the verification of the pre-sizing and for the electromagnetic behavior analysis of the PMSM. These were performed by using the ANSYS Motor-CAD software. All the obtained results emphasized that the pre-sizing of the PMSM was performed correctly, and the designed electrical machine can fulfill all the prescribed requirements. To highlight the superiority of the chosen surface-mounted PMSM topology, a comparative study was performed for four PMSMs having the same stator but different rotor topologies having the same quantity of permanent magnets. The study revealed that the PMSM with permanent magnets on its rotor surface is the best-fitting variant for the foreseen application. By intensively using the ANSYS Motor-CAD software, the authors appreciated that this product is a very useful tool in the hands of the designers not only in evaluating the machine’s computed geometry (by checking its correctness and feasibility), but also in its in-depth electromagnetic analysis and in calculating its parameters of interest.

Comparative analysis of the power parameters of a line start permanent magnet synchronous motor using professional FEM packages and in-house software

“…Very often, measurement verification of calculation results is presented to check the accuracy of the applied simulation models and computational software. The articles in question concern comparisons not only of the calculations of the electromagnetic field, but also of other physical fields, e.g., thermal fields, fluid flow fields, mainly in 2D [21][22][23][24][25]. Usually, the presented research results lead to the conclusion that there is a very high convergence of results obtained using different optical environments, e.g., ANSYS Maxwell or COMSOL Multiphysics.…”

Identification of Parameters and States in PMSMs

“…The great efficiency of PMSMs is one of their main benefits. This is caused by the rotor's use of permanent magnets, which does away with the requirement for a distinct excitation source [3]. The lack of a separate excitation source lowers the motor's total strength loss, increasing efficiency.…”
