Main Question or Discussion Point

Hi,

when a perment magnet machine is designed for a particular power but is operated at a much lower power, is it inefficient as with induction machines?

Thanks

No it isn't. That's why all small motors use permanent magnets.

There may be a misunderstanding here: a permanent magnet motor still uses electromagnets too.
