Or even more simplified. There are two different types of Electric
Motor, Inductive, which doesn't use carbon brushes to make it work,
and Power Tool Electric Motors that do use carbon brushes to make it
work.

Inductive loads have a huge variation in the voltage and current they
draw from a gennie, and cause the output to swing positive and
negative a lot more, especially on start up, than an electric motor
that uses carbon brushes to send the voltage and current through the
winding coils.

The table seperates them into two catagories of "Electic Motors" and
"Power Tools" and that's the only difference.

Simple.

It may be simple, but it totally fails to address the question about power
factor! Nowhere have you made any reference to phase angle between volts and
current - which is fundamental to the whole thing.

Startup current vs running current is an entirely different issue. Whilst it
needs to be taken into consideration, it has nothing to do with the question
which the OP asked - which was why the Power Factor was different for
different types of device.
