This innovative induction motor eliminates the use of rare earths thanks to its magnet-free design

A significant advancement in the field of sustainable technology has emerged with the development of an induction motor that eliminates the use of rare earths, thanks to its magnet-less design. This innovative approach aims not only to reduce environmental impact but also to address challenges related to the extraction and availability of these materials. At the core of this development are collaborations between leading companies that are redefining the future of electric motors.

The collaboration between Mahle and Valeo has resulted in a revolutionary induction electric motor that completely forgoes magnets and rare earth materials. This novel design, known as iBEE, offers high performance with low carbon emissions throughout its lifecycle, thereby reducing environmental impact compared to conventional motors. The innovative system promotes efficiency, sustainability, and is shaping up to be a viable alternative for the electric vehicles of the future.

A Strategic Alliance for Innovation

Mahle and Valeo, both leaders in electric motor design, have combined their expertise to create a brushless internal electric excitation system (iBEE). This joint project aims to eliminate the dependence on rare earths, materials that are not only costly but also difficult to extract and process. This collaboration stands out for its impact on the automotive industry, as it opens a path toward the production of more eco-friendly and sustainable motors.

Operation of the iBEE Motor

The iBEE motor replaces permanent magnets and internal brushes with an electrical induction system that maintains optimal performance. This not only reduces production costs but also minimizes maintenance. By avoiding scarce and fragile materials such as rare earths, this motor is an example of innovative engineering that optimizes resources and challenges traditional electric motor manufacturing methods.

Technology from Mahle and Valeo and Its Impact

The design of the iBEE is based on the cutting-edge technologies of both partners. Mahle was already recognized for its magnet-less MCT motor, while Valeo has been working on innovative stators and control systems. This new motor combines Mahle’s magnet-less rotor with Valeo’s motor control system, thus increasing energy efficiency and reducing carbon emissions, up to 40% lower than conventional motors.

Features and Advances of the iBEE Motor

The iBEE offers a power range of 220 to 350 kW, making it suitable for applications in high-end vehicles. Additionally, the implementation of an optimized cooling system is planned to improve the motor’s performance in terms of continuous and peak power. By adopting a clever and clean approach, this motor represents a significant step towards the future of sustainable mobility.

Projections and Future of the iBEE Motor

Mahle and Valeo plan to complete the initial tests of the iBEE prototype by the end of 2024. This next-generation motor marks a new beginning in the way electric motors are conceived, aligning with the sustainability and efficiency trends currently prevailing. This development could change the paradigm of electric vehicles, moving towards more accessible and environmentally friendly mechanisms.

The Future of Magnetless Electric Motors

The development of the induction motor without rare earths and its innovative magnet-less design marks a significant milestone in sustainable technology. The environmental and economic advantages of this approach are considerable, as it eliminates the dependence on scarce and costly materials that often prove problematic from both an economic and ecological standpoint. By avoiding the use of rare earths, these motors not only promote more sustainable practices in their manufacturing but also open new opportunities for the automotive industry in terms of cost reduction.

The collaborative design between Mahle and Valeo has demonstrated that the union of advanced technologies can lead to innovative solutions that benefit both manufacturers and consumers. The removal of magnets enhances the durability of the motors, thereby reducing maintenance and increasing overall efficiency. This results in more resilient and reliable vehicles, which is sure to attract the attention of manufacturers seeking to optimize their models for a cleaner future.

Furthermore, this technology adopts a unique cooling system, allowing for sustained performance even under maximum load conditions. This feature confirms its potential not only in electric vehicles but also in other industries where continuous and robust electrical performance is required. By reducing carbon emissions by more than 40%, this advancement underscores the importance of innovating to tackle current environmental challenges.

This motor represents a crucial advance towards the future of electric transportation, eliminating the need for permanent magnets and rare earths. Its introduction to the market will mark a turning point in the history of electric mobility, offering an efficient and responsible alternative that many have anticipated. The collaboration between Mahle and Valeo not only propels this new technological era but also sets a standard for future partnerships focused on sustainability.
