Thermal management becomes increasingly challenging - and more critical - when space is tight.

In this episode of Tech Torqs, we break down the fundamentals of thermal strategy for compact motor applications, where limited room for airflow and cooling components requires smart design choices.

Passive Cooling

• Use materials with high thermal conductivity and specific heat capacity
• Ensure efficient conductive paths to spread and transfer heat
• Leverage surrounding structures as heat sinks
• Apply high-performance thermal adhesives to reduce resistance

Active Cooling

• Integrate solutions like cold plates, heat pipes, water jackets, or focused airflow
• Use CFD modeling to identify hot spots and optimize heat removal strategies

Design-Level Optimization

• Minimize losses at the source with iterative motor design
• Optimize size, weight, and power consumption to prevent thermal bottlenecks
  ‍

Together, these steps form a holistic thermal approach that protects the motor from overheating, boosts performance, and ensures long-term reliability—even in the tightest mechanical envelopes.
