Core Loss Testing for Magnetic Performance
Core loss testing evaluates magnetic losses in electrical steel and motor cores to verify magnetic performance, energy efficiency, and compliance with specified requirements.
Core loss testing evaluates the magnetic losses and performance of stator cores to ensure the electrical steel and finished cores meet specified requirements. By identifying excessive core losses and material or process variations, testing helps support higher motor efficiency, stable electromagnetic performance, and consistent quality across production batches.
