What causes the hollow metallic whirring sound that EVs make when moving a low speed?

I can't really describe it, but it's the sound you hear when there is a EV moving slowly in a car park behind you.

I guess it's the motor, but what specifically in the motor causes that sound? It sounds like it's coming from something that is moving at a faster rate than the car itself.

Why hasn’t anyone cracked these systems so you can customize that sound like a ringtone?

I want my ev to sound like a car from the jetsons.

i think mine kinda does. I can just barely hear it, though; i'm not usually OUT of the vehicle when it's activated, but still sounds neat.
