Why high-performance electric motors start with the right coating thickness
Precisely measuring thin insulating coatings on electrical steel sheets – for superior quality and maximum performance in e-mobility
As e-mobility continues to grow rapidly, not only are production volumes increasing, but so are the demands on the performance and efficiency of electric motors. One key factor is the coating thickness of insulating varnishes on electrical steel sheets used in magnetic cores. Even the smallest deviations in the micrometer range can impact the electrical properties of this steel sheets – and ultimately the overall performance of the motor. Ensuring consistent quality therefore requires precise and reliable measuring technology.
In this Application Note you will learn, among other things:
- how to reliably monitor thin insulating coatings in the range of 0.5 to 5 μm
- why the beta-backscattering method is the optimal choice for this application
- how the right measuring technology helps you meet the highest quality standards
