eli5: What makes electrical motors in cars so quiet?

304 views

I mean in comparison with other motors, like power tools or even home appliances? Is it just sound insulation or is it a different kind of motor?

Combustion: explosions, noisy

Electric motors: no explosions, quieter but not noiseless.

If an electric vehicle seems completely silent it’s likely due to all the other noise around it from combustion vehicles.

Even with a “quiet” electric motor there will always be noise because of moving parts.
