ESC PCB layout - B-G431B-ESC1

[LarkinM96]

On the phase outputs why are there ground cutouts on the layout for this reference design. Is there a risk to cross couple to the ground plane with the switching noise or is it for thermal concerns?

I've seen this in several ST ESC designs for drones and wanted to know. 

Thanks,

Hello, can you precise which cut out you are speaking of ? Because in fact the cut-out you seem to refer is to put resistor on the other side .
