Lamborghini's New Tamario and Axial Flux Motors

Key Points

• Tamario Features: Lamborghini's new Tamario vehicle integrates three advanced motors, providing over 440 horsepower.
• Motor Origin: Concept first developed in 2005 at the University of Oxford; evolved significantly since.
• Applications: Used in powerful cars and the world's fastest electric plane.

Axial Flux Motors: Overview

• Created by Yasa: Founded by Dr. Tim Wulmer in 2009 after prototyping during his PhD.
• Electric Motors Basics: Use magnetic fields to create rotation; consist of a rotor and stator.
• Flux Types: Radial (fields flow radially) vs. Axial (fields flow along the axis).
  • Torque and Power Densities: Axial often has higher torque for given weight but not always higher power density.

Yasa's Advanced Design

• Yokeless and Segmented Armature: Innovative design removing the need for heavy iron yoke.
  • Structural and Magnetic Benefits: Reduces weight and improves efficiency.
• Permanent Magnet Rotors: Two rotors increase magnetic field strength and guide loops.
• Copper Coil Enhancement: Larger coils improve magnetic alignment.

Advantages of Yasa's Design

• Efficiency Improvements: Better cooling and magnetic flow due to segmented armature.
• Weight Reduction: 80% less iron in the stator.
• Performance Stats: Four times more torque, double the power density, 50% lighter, 20% of the radial motor depth.

Integration in Lamborghini

• Motor Design: Custom design for higher speeds (up to 10,000 RPM).
• Placement in Tamario: Two motors at the front axle for torque vectoring; one integrated into the V8 engine.
• Additional Benefits: Fills turbo lag, functions as starter motor and generator.

Technical Specifications

• Motor Weight and Size: Each motor weighs 17.3 kg and is 70 mm thick.
• Power Output: Each motor produces 110 kW (148 horsepower).
• Battery Pack: Small 3.88 kWh battery powering the motors.

Implications and Future Prospects

• Manufacturing and Production: Moving towards volume production to overcome historical challenges.
• Design and Manufacturing: Uses precision CAD tools (e.g., On Shape).

Conclusion

• Innovation and Genius: Yasa's design and Lamborghini's implementation showcase cutting-edge engineering.
• CAD Software Mention: On Shape, offering advanced design capabilities in the cloud.
