Abstract :
This paper illustrates some results about the experimental characterization of current carrying capacity (CCC) of printed circuit board (PCB) stator coils. Thermometric tests have been carried out with both DC and AC power supply, in order to evaluate the relationship between flowing current and coils temperature rise and quantify with experiments the impact of frequency related parasitic phenomena on coils overheating. Temperature spatial distribution has been also investigated by means of thermal-imaging techniques. A comparison between experimental data and the most spread guideline for PCB traces sizing is provided.
