I think that Tesla has gone to great extremes to shield the inverter and three phase motor to the extent that they use what is essentially high current shielded coax to get the DC battery power to the electric motors. The three phase inverter is mounted into the same housing as the three phase motor.

See:

and

The problem i suppose derives from the amps x high voltage of the motors and the pulse waveforms

all over the place. If the cars have metal bodies, i suppose this QRN is very localised; i think maybe

won't propagate much unless we go to composite car bodies?
