I remember reading a book about motors, and one of the more interesting
ones was referred to as a "Printed Pole Motor" IIRC.
I believe they are now used in high-end machining centers as a way
to get very wide speed ranges at full HP without using gearing or
belt drives. I think they are also called switched reluctance
motors. They do not use any permanent magnets, but rewrite the
poles on an iron rotor.

Apparently " printed" pole motors are now called "written" pole
motors. See this link:
http://www.meridiumpower.ca/C/c_1.html
for an
explanation.
Only called that by this maker. Note the (R) (registered
trademark symbol -- the letter 'R' in a circle) everywhere it is used,
and this note about ahla way down (where the (R) symbol is showing as
"\256" on my screen, showing that it is a non-printing character on this
system. But it may show up properly on yours.

And the printed motors which I have seen (and which I have a
few examples of) are DC motors, while these are AC for the standard power
line -- single phase or three phase.
Enjoy,
DoN.
I've hot a (big) handfull of printed circuit DC motors - some of
them complete with the servo tach mechanisms from old industrial
robots looking for an application. HEAVY little critters witk cast
steet? frames.
