Lamborghini has once again pushed the boundaries of automotive innovation with the Tamario, a hybrid supercar that integrates three innovative axial flux motors developed by Yasa. These motors, featuring a unique yokeless and segmented armature design, deliver unparalleled power density, torque, and efficiency. By embedding one of these motors directly into the V8 engine housing, Lamborghini has created a hybrid powertrain that not only eliminates turbo lag but also sets a new benchmark for electric vehicle (EV) performance. This new approach underscores Lamborghini’s commitment to blending high performance with advanced engineering.
What Makes Axial Flux Motors Unique?
TL;DR Key Takeaways :
- Lamborghini’s Tamario hybrid supercar integrates three advanced axial flux motors by Yasa, featuring a yokeless and segmented armature design for exceptional power density, torque, and efficiency.
- Axial flux motors offer higher torque density and improved efficiency compared to traditional radial flux motors, making them ideal for high-performance applications.
- Yasa’s innovative design eliminates the iron yoke, reduces motor weight by up to 80%, and incorporates dual permanent magnet rotors for enhanced torque and power density.
- The Tamario’s hybrid powertrain strategically uses two motors on the front axle for torque vectoring and one motor embedded in the V8 engine housing to eliminate turbo lag and streamline the hybrid system.
- A compact 3.8 kWh battery and advanced thermal management systems ensure optimal performance and reliability, showcasing the potential of axial flux motors to transform hybrid and electric vehicles.
Axial flux motors represent a significant departure from the more commonly used radial flux motors, offering distinct advantages that make them ideal for high-performance applications. Unlike radial flux motors, which generate a magnetic field radiating outward from the center, axial flux motors produce a magnetic field along the motor’s axis. This fundamental difference in design results in several key benefits:
- Higher Torque Density: Axial flux motors deliver greater torque in a more compact form, making them ideal for space-constrained applications.
- Improved Efficiency: The axial configuration reduces energy losses, enhancing overall efficiency and performance.
Yasa has taken this concept to the next level by eliminating the traditional iron yoke, a component that typically adds weight and reduces efficiency in conventional motors. This innovation results in motors that are lighter, more compact, and better suited for advanced automotive applications like the Tamario. By using these advantages, Lamborghini has been able to achieve a seamless integration of electric and combustion power, redefining hybrid performance.
Yasa’s New Design
Yasa’s axial flux motors are a testament to advanced engineering, incorporating several innovative features that set them apart from traditional electric motors:
- Yokeless Design: The removal of the iron yoke reduces motor weight by up to 80%, significantly improving the power-to-weight ratio.
- Segmented Armature: This design enhances cooling by allowing better airflow around the copper windings, reducing heat buildup and improving overall efficiency.
- Dual Permanent Magnet Rotors: These rotors amplify the magnetic field, resulting in higher torque and improved performance.
These innovations enable Yasa’s motors to deliver up to four times the torque and twice the power density of traditional electric motors. Each motor weighs just 17.3 kilograms and measures only 70 millimeters in thickness, yet it produces an impressive 110 kW (148 horsepower). This combination of compact size and high output makes Yasa’s motors a perfect fit for high-performance vehicles like the Tamario, where every gram and millimeter counts.
