Thanks for adding that — yes, you can do this with any electric motor; EV motors have simply been optimized for this purpose, and can generate power in the kW range. They have the necessary wiring for handling high voltage, along with built-in cooling tubing/conduits.

They’re as close to a drop-in-and-spin electrical generator as you can get. And unlike gas engines they don’t really ever wear out — so it wouldn’t be a surprise to see these become highly available and pretty inexpensive as EV uptake continues to increase, and as we finally start seeing huge numbers of current EVs being taken off the roads due to age in 15 years or so.
