HOW A MOTOR HOUSING FOR AN ELECTRIC RACE CAR WAS 3D PRINTED

The team’s original plastic motor housing had significant limitations in both heat dissipation and structural integrity. To address these issues, they transitioned to an aluminum motor housing, aiming to improve thermal management, reduce component weight, and strengthen the connections for cooling hoses.

This shift required close collaboration with engineers to optimize the design for performance and manufacturability. The new aluminum housing not only provided increased durability but also played a key role in enhancing the vehicle’s overall cooling efficiency.

Key Benefits:

  • Improved cooling capacity: An additional 250-500 watts of cooling power, contributing to a 7% increase in overall cooling efficiency.
  • Enhanced durability: Stronger hose connections and reduced wall thickness without compromising strength, thanks to aluminum’s superior mechanical properties.
  • Optimized for racing: Hybrid cooling, combining water cooling with airflow, to keep the motors running at peak performance.
