Tech Torqs #7: How Does Thermal Management Affect Motor Performance?
Thermal management is one of the most overlooked but critical aspects of motor design. In this episode of Tech Torqs, we explain how effectively managing heat inside a motor directly impacts performance, efficiency, and reliability.
November 6, 2025
When heat generated in the windings isn’t evacuated efficiently, temperatures rise, causing increased losses, reduced output, and long-term damage like demagnetization, delamination, or mechanical failure.
To minimize these risks and unlock better motor performance:
- Maximize heat transfer areas
- Minimize interface resistances
- Use high-conductivity materials
- Optimize for external cooling
- Reduce thickness along key thermal paths
A motor that stays cooler can convert more input energy into mechanical power, operate more efficiently, and last significantly longer.
