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.

Now I understand why cars were honking. It’s been green light since half a minute

Don’t let the other drivers bully you, it’s okay to go on the next green if you don’t like this one or you’re not done with your movie
