Session

Enhancing Thermal Efficiency — Innovative Overmolded Housingless Stator with Integrated Water Cooling

Case Study

Thursday, March 26

11:40 am - 12:10 pm

Live in Munich

Less Details

This presentation introduces an advanced overmolded, housingless stator system with integrated water cooling, designed to significantly enhance thermal efficiency in high-voltage e-drives. By replacing the aluminum housing with a lightweight, over-molded stator, the system reduces weight by approximately 3 kg while achieving up to 30% improved cooling performance. The integrated cooling system not only enhances winding cooling but also actively reduces temperatures in the rotor and magnets, improving overall efficiency and NVH characteristics.

Hear about:

  • Enhanced cooling which boosts thermal efficiency by 30%
  • Achieving a lightweight design by replacing aluminum housing with an overmolded stator without compromising durability
  • How these advancements boost efficiency, optimize NVH characteristics, and enhance the overall performance of high-voltage e-drives
