Teaching Method for Electrical Machines Focusing on Differences Between Simulation and Experimental Verification

In modern times, electrical machines are used in a wide range of fields such as home appliances and automobile industries, so it is important for the development of these industries to train engineers with knowledge of electrical machines at universities. On the other hand, companies generally use finite element analysis (FEA) to minimize the number of motor prototypes and experiments to reduce development spans and costs. However, FEA has many differences from the actual electrical machine. Therefore, it is important for designers to understand these differences at the design stage using FEA. However, as mentioned above, it is usually difficult in the industry for engineers who design electrical machines using FEA to experience multiple prototypes and experiments in companies. Therefore, in our laboratory, we are implementing education that actively incorporates prototyping and experiments into the research cycle. In this paper, we introduce a teaching method focusing on the difference between experiments and FEA in electrical machines, as well as laboratory equipment. Finally, using a student questionnaire, we consider its educational effect.
