The global technology company ZF Group will present its comprehensive line-of-wire technology products and ultra-compact , lightweight 800-volt electric drive systems , as well as more compact and efficient non-magnetic zero rare earth motors at the 2023 German International Automobile and Smart Mobility Expo ( IAA Mobility 2023) , fully demonstrating ZF Group’s strong technical reserves and solution capabilities in accelerating business transformation and leading the trend of software-defined cars and electric mobility.

Before the opening of the auto show, ZF also announced the development of a drive motor that does not require magnetic materials. Different from today’s magnetless concept of separately excited synchronous motors, ZF’s inner-rotor induction-excited synchronous motor (I2SM) can transfer magnetic field energy through the induction exciter in the rotor shaft, achieving maximum power and power while ensuring the unique compactness of the motor. Torque Density.

This advanced iteration of the excitation synchronous motor is an optimized solution for the permanent magnet synchronous motor. Currently, the latter is the most widely used in electric vehicles, but both require rare earth materials to produce. Based on the characteristics of internal rotor induction excited synchronous motors, ZF is setting new standards for extremely high production sustainability of motors, as well as high power output and motor efficiency.
ZF Group Director Stephan von Schuckmann said that ZF has achieved further innovation with this zero-rare earth magnetless motor. On this basis, ZF is continuously improving the portfolio of electric drive products to create a more sustainable, efficient and resource-saving mode of travel. All new ZF products follow this guiding principle. The ultra-compact, magnetless motor is a strong example of ZF’s strategy to achieve greater resource efficiency and sustainability by increasing the efficiency of electric drives.

The inner-rotor induction excitation synchronous motor with a powerful and compact packaging method not only does not require rare earth materials, but also eliminates the resistance loss generated in the traditional permanent magnet synchronous motor, and thus improves the electric drive efficiency such as high-speed long-distance driving.
Stephan von Schuckmann said: “The reason why we can continue to be competitive in the market is because ZF, as a company with a century-old history, has been constantly making progress. For example, ZF has historically been As a leading transmission manufacturer, our 8-speed automatic transmission is very famous in the market, but now we are also continuing to electrify it according to the needs of the market. We have differentiated ourselves from our competitors. Compared with them, our electric drive The system has many advantages, and we are constantly improving its efficiency. We believe that only through continuous innovation can we stay at the forefront of the market.”
