Multi-Stage Design and Analysis of a Permanent Magnet Synchronous Machine with Parallel Comparison Tracks

A design and analysis process with two parallel softwares tracks is utilized to design a permanent magnet synchronous machine (PMSM) and evaluate its electromagnetic performance. In this process, a 50kW reference PMSM is designed and its characteristics including efficiency map, torque, flux linkage, back-EMF, radial flux and force density, core loss, as well as reduced order model (ROM) are compared. In parallel tracks, three different commercial finite element method (FEM) softwares i.e. Ansys Maxwell, Motor-CAD and JMAG Designer are utilized as the tools. The results show a good agreement between these tracks, while the track with JMAG has better performance regarding solving speed.
