In the study of magnet machines, the research for ultimate control is a fundamental point. For this research, CEDRAT proposes three methods.
As Cedrat explains in this paper, the permanent magnet synchronous motor (PMSM) is becoming popular in high-performance applications as compared with other types of AC motors. A short circuit between turns is the most critical fault in a machine; it is quite difficult to detect and almost impossible to remove. There are a number of techniques used to detect turn-to-turn faults.
In recent years, the requirement for accurate virtual design has grown constantly. However, greater computational efficiency means less time to get results while performing rapid, detailed analyses on a device. The overall goal is to have a streamlined, automated and customised model creation and simulation process. This is even more important with FEM software, where simulation run times are usually very high.
Analytical methodology remains the most important daily work tool of motor designers. The use of analytical tools is important because it reduces calculation time — especially during optimisation. However, there are some important phenomena that are not always evaluated, particularly when ECM (equivalent circuit models) are involved. For these, numerical methods derive the best results. The use of finite element analysis is very important because it provides detailed simulation and ...
