The origin of tensor analysis started with Dr. Kron of GE (General Electric), who began writing a series in the “General Electric Review< in April 1935 that continued until 1938. Meanwhile at Chubu University, the late Emeritus Professor of Electrical Engineering, Kunihiro Kato, presented a number of in-depth papers on tensor analysis and related topics. Building from these papers, we are working to develop a consistent means of theoretical analysis for synchronous, induction, and permanent magnet synchronous machines based on tensor methodology, while further carrying out related characteristic calculations. Such theoretical analysis is unique in that not only is the derived torque component valid without variation over time, but vibration components and frequencies which vary over time can be calculated as well. This methodology has an important role in the analysis of rotating machine characteristics. The desire for rotating machines with low vibration and noise levels means vibrating torque component analysis is important, as is finding a way to lessen the aforementioned levels. We expect to sere such improvements and further believe they will lead to improved performance of rotating machines. In this paper, we give an example of tensor analysis for synchronous and induction machines, introducing the analysis procedure and its features.
