" once visited the EE department at Glasgow university and they
demonstrated
a spinning "Beer Can Of Columbus" that worked off single phase current.
It
used two coils 90 degrees apart with one fed directly from the line and
the
other fed via a capacitor. I think they used low voltage AC like 24v or
similar."
That was two-phase excitation so there was indeed a rotating field;
the current in the arm with the capacitor led by ~90°.
