    The issue is the motors generate EM emissions that interfere with AM reception. To still have AM, they have to add shielding, which adds cost, as well as weight that will reduce range and efficiency.

      An AM radio receiver would easily fit in the palm of your hand. You could shield it with material that weighs no more than a pound.

        You can’t just shield the radio. That’s not where the antenna is. You have to shield the electrical components generating the interference.

      OK, it might cost a bit to install shielding, but it is not like a heavy thing - for AM can be done with metal net with rather large cells, which weights nothing and requires zero additional power.
