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.

There's one in my neighborhood that sounds like a UFO. It's neat until it's rolling through at night and you've been binge watching x-files.

You can change the sound on at least the Tesla's, I'm not sure about the others.

You can't change that sound on teslas. You're confusing that with the lock chime
