TranscriptWelcome to the exploration of a groundbreaking technology set to transform electric vehicle propulsion—the axial flux motor developed by YASA. This revolutionary motor technology is a modern twist on a concept that dates back over two centuries, to the inventive work of Michael Faraday.
Axial flux motors have historically faced manufacturing and cooling challenges, rendering them less common than their radial flux counterparts. However, the recent advancements by YASA have begun to address these issues, paving the way for wider adoption in electric vehicles, both in the high-performance sector and the mainstream market.
The significance of this innovation has not gone unnoticed. Mercedes-Benz's investment in YASA is a testament to the potential of axial flux motors to revolutionize the automotive industry. The iconic Mercedes-Benz Vision One-Eleven concept, a battery-powered homage to the revolutionary C111, showcases the capabilities of YASA's axial flux motors, hinting at a future where electric propulsion takes center stage.
The story of YASA is rooted in academia, where CTO Tim Woolmer's PhD research at Oxford University led to the founding of the company. Woolmer's inquisitive nature and pursuit of an electric motor ideal for an emerging market of electric vehicles resulted in YASA's unique design, overcoming the traditional barriers associated with axial flux motors.
The soft magnetic composite material played a crucial role in this breakthrough, enabling the production of three-dimensional laminations that were previously unattainable, thus resolving some of the fundamental manufacturing challenges. The innovative design not only significantly reduced the weight and size of the motors but also increased their torque density and efficiency.
YASA's motors have proven their mettle in the demanding world of motorsport, notably at the Pikes Peak race, where an electric vehicle equipped with their technology outperformed combustion engine competitors. This victory underscored the potential of electric propulsion to disrupt not just racing but also the broader automotive landscape.
As these motors continue to evolve, the benefits become even more pronounced. With advancements in cooling techniques, YASA's axial flux machines can sustain high power output, facilitating a reduction in size of up to 70%. This compactness offers exciting possibilities for vehicle design, including the potential for in-wheel motor applications, fundamentally altering vehicle architecture.
The acquisition of YASA by Mercedes-Benz marks a pivotal moment, allowing for the upscale production of axial flux motors and bringing this once niche technology to the forefront of the electric vehicle revolution. With the combined expertise of Mercedes-Benz and YASA, the future looks electrifying, promising a new era of performance and efficiency for battery electric vehicles. Transitioning from the broad strokes of YASA's impact on electric propulsion, let's now journey back to the genesis of axial flux motor technology and the pivotal role YASA played in its evolution. The axial flux motor, a concept that harkens back to the early days of electromagnetic discovery, has come full circle through YASA's innovative efforts.
Early axial flux motors encountered significant challenges that limited their widespread use. Chief among these were the complexities of manufacturing and cooling. Traditional manufacturing methods were not suited for the unique structure of axial flux motors, and their thermal management was less efficient compared to radial flux motors, which hampered their performance.
The academic roots of YASA are deeply entwined with the story of these motors. It was Tim Woolmer's PhD research that set the foundation for YASA—a quest to reimagine electric propulsion with a "blank-sheet-of-paper" approach. His investigation unearthed the inherent advantages of axial flux motors, such as superior torque and power density, and a smaller, lighter design compared to radial flux alternatives.
However, realizing the full potential of axial flux motors required innovative solutions to their manufacturing and cooling challenges. The breakthrough came with the utilization of soft magnetic composite materials, which heralded a new era in motor production. This material allowed for the creation of complex three-dimensional shapes through a simple press operation, circumventing the previous limitations in manufacturing axial flux motors.
YASA's approach to solving these issues has the potential to significantly alter the electric vehicle market. With the ability to produce axial flux motors that are not only more powerful and efficient but also easier to manufacture, the doors have opened for these motors to be used in a broader range of vehicles.
Moreover, the advancements in cooling technology developed by YASA have resolved the thermal management issues that once plagued axial flux motors. By creating a sealed structure filled with oil that flows in a zigzag pattern directly contacting every heat-generating component, YASA's motors can maintain high performance without overheating. This innovation in cooling not only ensures reliability but also contributes to the motor's reduced size, as there is no need for a bulky iron stator yoke.
The implications of these advancements are profound. As axial flux motors become more accessible and scalable, thanks to YASA's technology, electric vehicles can benefit from the motors' higher efficiency and reduced weight. This translates into longer ranges and better performance for electric vehicles, making them more appealing to a broader audience.
Furthermore, the smaller size of YASA's axial flux motors opens up new possibilities in vehicle design, such as the exciting prospect of in-wheel motor applications. This could lead to a reimagining of vehicle architecture, with more spacious interiors and flexible design options.
