Blimey! Thanks for the explanation Stefek.

Could you please explain why a motor which runs at a lower that nominated
voltage, draws more current to keep the power output the same?

very good explanation here
http://www.ecmweb.com/ar/electric_highs_lows_motor/

It doesn't really explain why a motor doesn't behave like a resistive
load; it states 'it does this' but glosses over 'why'.

To be fair, I think the article assumes a backrground knowledge of electrical
engineering. Where term like "power factor" and "magnetic saturation"
would be concepts the reader is expected to know about beforehand.
