Redesigned Motor Flange Delivers 70% Weight Reduction and Breakthrough Cooling Performance

Written by Pelagus Blog | Jan 5, 2026 7:11:01 AM

Client & Context: 

Servogear, a provider of propulsion systems, needed a custom flange solution to address persistent overheating in their electric motor during high-demand operations.

 

The Challenge: 

The standard flange between the diesel engine and electric motor did not deliver sufficient cooling, causing frequent overheating and risking operational disruption—especially during extended use in boost mode.

 

The Solution: 

Using Laser Powder Bed Fusion (LPBF) in aluminium, the flange was redesigned to integrate passive cooling fins based on topological optimization. This increased the surface area, improving heat dissipation and overall system performance. The switch to aluminium also reduced weight significantly.

 

The Results: 

  • ~70% weight reduction: from 8kg to 2.1kg
  • Improved passive cooling via surface-optimized fin design
  • Withstood continuous boost-mode operation for 1.5 hours
  • Delivered in just 3 weeks
  • Customizable design compatible with multiple motor and mount types

 

Client Testimonial:

“I am impressed by the remarkable durability of the additively manufactured flange we recently installed. It withstood continuous operation in boost mode for an unprecedented 1.5 hours. The quality of this flange has surpassed our expectations, setting a new benchmark for cooling performance. We’re excited about the possibilities of additive manufacturing in future projects.”

Why It Matters:

This case demonstrates how on-demand manufacturing empowers OEMs to tackle persistent performance issues with highly customized, engineering-led solutions. By combining design freedom, material optimization, and rapid turnaround, additive manufacturing unlocks new levels of reliability and responsiveness—especially for critical systems under thermal stress.
