Induction heating application cases by industry: Electric Vehicle (EV) manufacturing
Decarbonization in the manufacturing process: An example of the application of induction heating (IH) in the EV manufacturing process.
Here are some examples of the application of induction heating in the EV manufacturing process. - Shrink fitting of the housing and stator The stator is fitted into a lightweight aluminum housing through shrink fitting. The aluminum housing is heated to 200-300°C due to the interference fit between the housing and the stator, allowing the aluminum to expand and making it easier to place the stator inside the housing. - Shrink fitting of the steel shaft inside the rotor The rotor inside the stator of the electric motor is made of laminated steel to suppress heat generation from eddy currents during operation, as it is difficult to remove the heat generated. Induction heating coils can be designed to heat the steel from the outside or the inside. - Drying of the steel rotor After being machined to the tight tolerances required for efficient motor operation, the steel rotor assembly is heated by induction heating to remove the machining fluid. Induction heating allows for precise control of the rotor's temperature through closed-loop control. There are several other application examples as well. *For more details, please download the PDF or feel free to contact us.
basic information
General EVs have about 90% fewer moving parts compared to internal combustion engine vehicles. Induction heating (IH) is expected to contribute to the decarbonization of manufacturing processes and the improvement of working environments. Induction heating (IH) often excels in terms of reproducibility, accuracy, and efficiency compared to traditional heating methods that use flames or furnaces. *For more details, please download the PDF or feel free to contact us.*
