PM steppers work well as low power alternators.
They have many more poles than a typical small BLDCM do higher output
per rev (danger ...).

They are however usually very coggy (high saliency) which makes them
harder to start in very low energy input situations.
In some cases that matters, often it doesn't.

Lack of brushes is nice.
Any BLDCM will work for many values of work.
