> Where is it being generated The motor controller is turning the motor on and off rapidly in this frequency range to control the power in each winding. The inductance of the motor converts this to a near-constant amount of power. > cage that can be built around the motors The motors already have shielding and the wiring does, too. But when every car has peak RF output of hundreds of kilowatts, not too much of a fraction has to leak out to completely jam the AM band.
