Development Process and Technology Trend of Permanent Magnet Motor System for Electric Vehicle

Beyond the 4th industrial revolution, the beginning of the eco-friendly era has begun. Carbon neutrality with the last means regarding to climate change, has begun. In this reason, the electric motor industry rapidly emerged as the center of the industrial trend toward zero carbon. In particular, the eco-friendly automobile industry is the center of change for the automobile drive system. In other words, the driving core of automobiles is in a state of great transition from the internal combustion engine to the electric motor. In this paper, the development process of the motor drive system, which is the core technology of eco-friendly vehicles, and the design verification case of the motor system using CAE are described. Finally, the future technology development direction for the motor drive system of eco-friendly vehicles are introduced.
