Induction Motors and Permanent Magnet Motors in Electric Vehicles: Characteristics and Development Trends

This paper provides a review of the application of induction motors and permanent magnet motors in electric vehicles, discussing their characteristics, advantages, and disadvantages, as well as their development trends. The induction motor, invented by Nikola Tesla in 1887, operates based on the principles of electromagnetic induction and is widely used due to its simple and reliable structure, low cost, and processing difficulty. The permanent magnet motor, on the other hand, has a higher efficiency and power factor, making it increasingly popular in electric vehicles and other applications. The paper also discusses the design and working principles of both types of motors and identifies areas for further development, such as improving efficiency and power density, and enhancing control technology. Overall, this paper provides a comprehensive overview of the current state and future prospects of electric vehicle motor technology.
