Abstract
With the advancement of electrification and the use of wide bandgap power devices, which is one of the keys, it is necessary to analyze and evaluate the frequency range from DC to over 100 kHz electrically and magnetically. On the other hand, except for a part of problems in the high-frequency range such as axial voltage and surge voltage, analyses and designs of the motors have been promoted by nonlinear eddy current fields simulations in the low-frequency range in the past. In the frequency band above 100 kHz, the capacitive behavior caused by the motor structure and the low-frequency range behavior cannot be separated, and the possibility of system design with the inverter increases.
Based on the background, the presenter will describe the issues regarding the analysis and the design of the motors and their systems. In the presentation, examples of both the wide frequency band motor models and related noise analysis for the motor system operations will be shown.
